The Illnesses and Death of Queen Mary I

Queen Mary I in 1554, a copy of a portrait by Sir Antonis Mor

“My health is more unstable than that of any creature and I have all the greater need to rejoice in the testimony of a pure conscience.” Letter from Mary to the council of her brother King Edward VI, January 1552

It is always an interesting exercise to analyze the evidence presented for a person in history to come up with theories about their health. Of course retrospective diagnoses are impossible but we can garner clues to give us the ability to speculate as to what was happening. Queen Mary I’s brother Edward and half-brother Henry Fitzroy may have died of suppurating tumors of the lung or that old standby, tuberculosis. Her sister Elizabeth we know had decaying teeth causing toothache and a bout of smallpox that nearly killed her. Elizabeth also used makeup with a high content of lead that probably wasn’t good for her overall health.

From reading historical accounts we can develop a litany of symptoms Mary suffered from the time she was a teenager all the way to her death at age forty-two in 1558. In addition to these repeatedly frustrating and frequently debilitating illnesses, Mary lived in a state of stress and nervous tension from the time of her father’s decision to extricate himself from his marriage to her mother Catherine of Aragon which made her ability to deal with her illnesses even more difficult.

Mary’s appearance was described as thin and frail with a low-bridged nose, red hair and a fair complexion with light colored lips. She had a loud, deep voice. Her eyes were grey and she was extremely shortsighted like her father, a trait that caused her to have a penetrating gaze. When angry, she had a quick temper. She was stubborn and didn’t like to be crossed.

There is nothing to suggest Mary’s health was a considerable problem before she entered puberty. She most likely had the usual childhood illnesses but overall was healthy. She would have lived a pampered life with people to watch over her, a good diet and copious exercise as well as receiving a classic humanist education. In the spring of 1528, Mary had a bout of smallpox but survived unscathed.

When Mary entered puberty at the age of fourteen, she began to suffer from pains in her head and stomach. There would be times where she couldn’t keep down her food for eight or ten days. In these instances, her mother’s apothecary and physician were called in to treat her. She was diagnosed with “strangulation of the womb”. This covered a wide range of symptoms that included amenorrhea (the irregularity or cessation of menstrual periods), a depressed mental state indicated by heaviness, fear and sorrowfulness, difficulty breathing and pain and swelling of the abdomen. Other signs of the illness were headache, nausea, vomiting, and lack of appetite, trembling of the heart, fainting, melancholy and fearful dreams.

Before Mary went to live with her new half-sister Elizabeth, she engaged in regular horseback riding as part of her treatment. Once she was moved to her sister’s household, this was stopped. Her guardian, Lady Anne Shelton couldn’t allow Mary the freedom to ride and risk her making an escape. In late 1534, Parliament had passed the Act of Succession and it was being enforced with increasing harshness. Everyone was required to swear an oath, including Mary. The oath compelled Mary not to call herself Princess or her mother Queen at the risk of being put in the Tower or even death.

Shortly after this, several weeks before Mary’s nineteenth birthday, she became seriously ill. She lived in an atmosphere of severe strain under the care of Lady Shelton. Mary complained of headaches and indigestion and was basically prostrate. Lady Shelton called in an unfamiliar apothecary who prescribed pills which made Mary’s condition worse. This may have been an allergic reaction to the medicine or Mary could have had a psychosomatic response. Lady Shelton was terrified she would be accused of poisoning Mary.

With no one wanting to be blamed for her death, there was a reluctance for anyone, Imperial or royal to treat her. The Imperial ambassador Eustace Chapuys eventually got through to the King’s secretary Thomas Cromwell and he agreed to send the king’s personal physician Dr. Butts to see Mary. Dr. Butts advised the king that Mary’s sickness was not incurable and with diligent and careful treatment and improved living conditions she would get better.

Needless to say, the king refused this. Mary did recover somewhat but had a severe relapse in mid-March. By late March she was still convalescent and was eating a special diet with extra meat at uncustomary times of the day. Eventually she recovered at Greenwich. In the fall of 1535, Mary’s illness returned and doctors were called in to treat a rheum in her head.

Mary’s illnesses did not appear with a consistent pattern or conform to a known disease. Her bouts of amenorrhea and melancholia were basically seasonal with the greatest severity in the fall and early spring but it could also occur in the summer and winter. The usual symptoms did not appear every year or at least it was not severe enough to be mentioned. The symptoms could vary widely with each event. News of Mary’s frequent illnesses traveled throughout the kingdom and over to the continent. Her health had a deleterious effect on her marriage prospects. Ambassadors and those who were deliberating about making a match with her wondered about her ability to bear children.

When Mary was under pressure by her father and Cromwell to absolutely submit to the king’s will, Mary mentioned to Cromwell in a letter she was having headache, toothache, neuralgia and insomnia. Treatments prescribed would have included tooth pulling and bloodletting from her foot or other areas of the body. The bloodletting could have led to anemia.

Mary finally did sign her submission on June 22, 1536 and was admitted into her father’s household. Shortly after she served as chief mourner at the funeral of Queen Jane Seymour, Mary had a severe toothache. Her father sent his physician to have the tooth extracted. Mary was seriously ill again in December 1537 and January 1538 for several weeks. She was so sick she could neither sit nor stand and spent time in her bed with faintness. The physicians were cautious in treating her once again and Dr. Butts was consulted. In March and April of 1542, she suffered from a strange fever which made her weak and caused heart palpitations. She was so debilitated it appeared as though she was dead. Chapuys was worried she was in extreme danger and King Henry frequently inquired about her condition. By the first of May she was out of danger.

In the summer of 1543, King Henry married his sixth and final wife, Catherine Parr. Mary accompanied them on the honeymoon but soon became ill and had to turn back. She recuperated in the company of Edward and Elizabeth and looked after her own servants who were more ill than she was. In May 1547, Mary was having intermittent bouts of fever. With each fever, her mental state and melancholy would worsen. In the last years of her father’s reign, she mentions toothache and neuralgia along with the customary melancholia.

Under the reign of her brother King Edward VI, Mary was once again under extreme stress. Edward, who was Protestant, was pressuring her to cease and desist from hearing the daily Catholic mass. Of course Mary refused as it went against her conscience. Relations between the brother and sister were tense and Mary would have bouts of her illness. In a letter to her brother, she described how she had a catarrh in her head and it greatly pained her to bend her head down to write him.

When Edward died, Mary was forced to make a power play to depose Jane Grey who had been declared queen by some of the nobility. Mary was triumphant and made her rightful claim to the throne. She was now the first crowned Queen Regnant of England. One of the first orders of business was to marry. It was suggested by her cousin, Holy Roman Emperor Charles V that she marry his son Prince Philip of Spain. Philip and Mary were married on July 25, 1554.

Soon after the nuptials, the thirty-seven year old queen declared herself pregnant. Philip decided to await the birth of the child in the spring. Curiously, Mary’s health improved with this purported pregnancy. As the due date approached, Mary withdrew into her chambers to await the birth at Hampton Court. On April 30, 1555, it was announced the queen had delivered a child and wild celebrations broke out in the streets. Soon it became clear this was a mistake. The doctors said there was a miscalculation of the date and her servants kept up the pretext.

Mary persisted in believing she was with child and became more and more reclusive. She would sit for hours wrestling with depression and anxiety. She looked pale and ill to those around her. She assumed the position of sitting on cushions on the floor with her knees drawn up to her chin, most unusual for someone who was supposedly pregnant. Eventually, Mary accepted the reality there was no child. By May 21, the swelling of her belly had gone down and her health improved. The pretext of a delivery was kept up until July when Mary moved the court to Oatlands so Hampton Court could be cleaned. This was an episode of pseudocyesis, commonly known as “phantom pregnancy”.

Philip left England for the Low Countries after this, leaving Mary alone to rule her kingdom. He would return to England from March through July of 1557. Shortly before his arrival, there was rebellion in the realm. Mary feared assassination and complained of insomnia. Some commented that she looked ten years older than she was. She became ill again with melancholia and insomnia. Philip left England for the last time. Mary thought she was pregnant again. No one believed her this time. Her belly was swollen with what may have been a dropsy. Eventually, talk of her pregnancy was no longer mentioned.

Mary recovered but in January of 1558, England lost Calais on the continent to the French. The country was experiencing unremittent torrential rains, ruining crops and creating famine. On top of this, a vicious strain of influenza was killing people at the rate of the plague. This illness was not like the sweating sickness where people died within days if not hours. The disease lingered for long periods before the victim died.

In the spring and summer, Mary was sick again with melancholia and insomnia. In August, she had a low fever and dropsy and was in such grave condition, she was moved from Hampton Court to St. James Palace. By September, Mary had a high fever, headaches, and periods of confusion along with an almost complete loss of vision. She would sink into a fever for a few days and then revive in a chronic pattern. Waves of depression became more frequent making her illness worse.

In October it became evident this illness would be her last and she made a codicil to her will. She still had short periods of rationality and at times was able to work with the council. In the third week of October, Philip received news from England that she was gravely ill. He sent his personal physician.

In early November there was some relief in her condition. On the 8th, she agreed to name Elizabeth her successor and then awaited death with paroxysms and long periods of unconsciousness. As she grew weaker and weaker, nobles, officials and household officers began to desert St. James for Hatfield where Elizabeth was staying. She was essentially blind and could no longer read. Those servants who were faithful surrounded her bed in grief. She would pray for her own salvation and describe her joyous dreams to them when she was lucid. She saw many little children playing and singing like angels before her, giving her great comfort.

Mary heard mass in the early hours of November 17. Then between four and five in the morning, she died so peacefully that her servants thought she was better. But the attending doctor knew she had passed away.

Possible Diagnoses for Mary’s Illnesses

One theory regarding Mary’s phantom pregnancies points to a condition known as ovarian dropsy. In this condition, a cyst forms on the ovary and gradually enlaces itself until it becomes, in some instances, a great size and fills with fluid. Cysts can be painful and produce widespread abdominal pain. The causes of the dropsy are obscure. In some cases, the condition can be attributed to inflammation of the ovary. The ovary can also be subject to the growth of various other tumors such as fibrous or cancerous tumors and also cause deformation of the ovary, leading to infertility. Ovarian dropsy usually lasts for a few years.

Prolactinoma Pituitary Tumor

Dr. Milo Keynes wrote an article on this subject for Journal of Medical Biography in 2000. After careful consideration of the historical evidence, Keynes believed Mary’s symptoms indicated a tumor on the pituitary endocrine gland. These tumors are typically benign and can press on surrounding structures such as the optic nerve, leading to blindness and headache. The gland will also create an over-secretion and under-secretion of hormones. In this case the hormone involved is prolactin. In excess, prolactin can cause infertility, amenorrhea, infrequent and irregular uterine bleeding and galactorrhea (swollen breasts that secrete milk). The tumor can also cause depressive disorders.

Most significantly, patients with this type of tumor have been diagnosed with pseudocyesis or “phantom pregnancy”. A non-pregnant woman has a delusional belief that she is with child. The patient will manifest the signs of pregnancy such as weight gain, increase in abdominal girth, the sensation of fetal movement, vomiting, nausea, aberrations of appetite and galactorrhea.

Enlargement of the tumor can also affect the function of the thyroid gland and create the condition of hypothyroidism. Symptoms include rough, deep voice, loss of hair and eyebrows, flushing of the cheeks, dryness and thickening of the skin, constipation resulting in an extended abdomen, increase in weight, chronic anemia, headaches, depression and mental confusion.

Keynes discusses the portrait of Mary above which was painted in 1554 when Mary was thirty-eight. He notes the portrait signifies Mary had flushed cheeks and a pudgy face, pallor to her skin, the loss of her eyebrows and a receding hairline. All of this is indicative of a deficient secretion of the thyroid gland.


Did Mary have influenza and is that what killed her? Due to the particularly virulent outbreak of the flu at the time, it’s entirely possible Mary did contract the flu. Some in her household had it and it was highly contagious. People with this flu lingered for some time before dying and it took Mary several weeks to succumb. It is entirely possible that Mary suffered from the above mentioned diseases already and then caught the flu, leading to her death. We will never truly know but there are many tantalizing clues to make some educated guesses.

  1. My dog had a false pregnancy before we got her fixed. She even started secreting milk. Then her symptoms abated; we got her fixed; and she never “got pregnant” again.


  2. Sounds like depression (mental illness) spurred on most of these maladies.

    The phantom pregnancies could have been related to endometriosis (and consequently ovarian cysts), as I suffer from it myself and the swelling of the abdomen can be very severe at times. Not to mention excruciatingly painful.


    • AMEN, SISTER! I had dreadful cramping, cysts, & endometriosis, starting at a very young age (10), and though my maternal family believed me, my paternal grandmother did not, and complained that I was seeking attention. It was like a slap in the face. Many female teachers were in Grandma’s camp. If it didn’t happen to them, it didn’t exist. It was hell until my doctor put me on the Pill at age 16, when it was discovered that the Pill often relieved menstrual pain.

      I can only imagine being in Mary’s position. The pain & heartache, following years of abuse & neglect. No one knew what we now know about uterine conditions, and many probably mocked her in secret. She was monarch, but probably felt very alone, terrified, and fearing she was letting her people down. What royal council of those days could offer any help or encouragement? A woman could rule, but she could not share with her council what she was going through.

      Her father became crueler as his pain and perceptions worsened. Mary did likewise, perhaps believing in her heart of hearts that eradicating Protestantism was the only way God would remove her afflictions.

      Uneasy is a nation when its monarch’s pain, physical and mental, cannot be allayed!


    • My thoughts exactly. I had endometriosis, which could definitely play a part in her symptoms. I also developed a very large ovarian cyst (about the size of a soccer ball), which could easily be mistaken for an early pregnancy.


  3. This is a fascinating article, although it is indeed sad that this woman was so ill treated and suffered so many maladies.

    I am rather surprised that endometriosis has not been raised as a possible contributor to Mary’s ill health, especially given the timing of its onset.

  4. Mary’s trouble to conceive may have been inherited. Her mother had trouble carrying to full term. This probably played a huge part for her depression and stress. There was a great deal of pressure for women to give birth especially in the nobility class. During this era women got blamed for not conceiving even if it wasn’t their fertility problem.

    • So true! Women were only seen as empty vessels to receive the man’s “seed”.
      What characteristics a child might inherit from a mother were seen as “marks”.
      If she bore a disabled child, it was blamed on the “mark” caused by having laid eyes, listening to, touching, or even touching SOMETHING touched by a disabled person!. That a child would bear many resemblances to its mother’s family was seen as marks by frequent & close association. A child was only of a mother’s “blood” due to the “sharing” of blood in the womb. Everything else was of the father!

      Woe to the child with little resemblance to the father! This was cause enough to doubt the wife’s faithfulness! While any child born in wedlock was lawfully the husband’s, it might suffer for being a blond in a family where both sides were mostly brunettes. Genetics was little, if not at all, understood. And, in a time long before photography and of shorter lifespans, it was easy to forget that great-great-grandma on father’s side was very fair!

      It was assumed all male “seed” was healthy. Because women were considered weak in body & mind, blame for childbearing problems lay at their feet. Men gave scant consideration to family history, theirs or their wives. They also didn’t see women’s physical health as much of a detriment, unless they were clearly doing poorly; remember those “marks”!

      Childhood illnesses & deaths were the deemed the results of the physical world around them. Since autopsies of Christians were strictly forbidden, and EVERYONE was baptized at birth, little knowledge of anatomy was known. That animal physiology could have similarities was blasphemous. Man was made in God’s image; animals were not.

      I sincerely doubt that it ever crossed the minds of Henry VIII or Philip of Spain that any of the blame for their children’s health woes could be laid at THEIR feet!

    • Catherine of Aragon carried two children to full term. Woman often had miscarriages and stillbirths. Isabella of Castile, Catherine of Aragon had five children and many stillbirths and miscarriages. Maria of Aragon who was a sister of Catherine of Aragon and the second wife of Manuel of Portugal and the mother of John the Third of Portugal had nine children, all of which survived. So Mary the First’s trouble was not inherited. Of coarse, there was pressure. The whole point of weddings was to cement alliances between two countries. And it was not only in this era but all throughout history that women got blamed. Back then, it was not known that men carried the y cromozone and determined the sex of a child.

  5. Absolutely fascinating and superbly researched, as always. I don’t suppose Mary has many fans (certainly not in the UK) and I must admit I always thought she was something of a hypochondriac, but you have to feel a bit sorry for the poor lass.

  6. I have always been interested in Mary and wondered about the reasons for her poor health. You actually wrote about more of her many illnesses than I knew about. I enjoyed this article and now have a better understanding of the illnesses she suffered with, It only makes me feel sadder for the poor woman than I did before.

  7. Fantastic read, however the condition described above as an under -active thyroid with hair loss and lack of appetite, etc, is called hypothyroidism, not hyperthyroidism.

  8. Mary didn’t have headaches until puberty which is when migraine headaches usually begin. With the amount of stress, it could be another diagnosis for her ill health.

    • Absolutely! Puberty is the root of many ailments women suffer. It affect bones, hormones, weight, & a plethora of health issues. For centuries men just called it hysteria, from the same Latin root which hysterectomy is derived.

      I remember a professor telling my class that if men experienced menstruation, they would attribute it to positive proofs of masculine superiority. Since it is a female thing, it was denigrated & degraded. Only when a woman was bearing children did she have value. Otherwise she was an empty vessel & a liability.

      Once the Hapsburgs took power in Spain, the only queens worthy of burial in the royal vault were those who bore an heir. I wonder what Isabella would have thought? These were her descendants!

  9. Henry VIII was unbelievably cruel to his female children, especially Mary! I have always maintained that Mary suffered for all female English monarchs. It was so inconceivable that England COULD be ruled by a woman, that Henry wasted precious time & resources in his quest for a son. So many lives were lost — not just wives! Mary made it possible for women to rule in their own rights. She paid dearly. No other queen has had to suffer so much for right to the throne.

    That no English contemporaries seemed to notice the abilities of Mary’s grandmother, Queen Isabella, is a testament to prejudice. An English woman’s royal rights through lineage were supported, while her actual right to rule was denied. Though Isabella and Ferdinand ruled jointly, Castile was still hers, alone, and he had no rights to the country. After Isabella died, Ferdinand had their eldest daughter, Juana, declared insane (after years of abuse by her husband), so he could control Castile. Catalina, Mary’s mother, was an accomplished & well educated woman. She simply could not bear a healthy, male heir, and Henry wouldn’t accept that a woman could rule in her own right. Sadly, none of Isabella’s daughters were able to escape the manipulation & domination of their menfolk.

    Mary had much potential, but she was treated so cruelly it is no wonder her physical ills were exacerbated. She suffered more & longer than Elizabeth. How might Elizabeth have fared had she experienced what Mary did? The differences between the queens, however, were fundamentally different & complex. Knowing the whole story of Mary, and what she endured, lends a sympathetic outlook on one merely remembered as “bloody.” Certainly she was no less of that than her father!

    Mary’s medical woes were very real. No one really knew what went on inside a human body, as anatomical studies were forbidden. Many things can adversely affect women’s reproductive organs, and on top of the congenital illnesses, filthy hands and instruments were often used by doctors & midwives, and husbands often carried venereal diseases, germs & bacteria that played havoc on immune systems. Mary probably had her share of such invasions to her reproductive health.

    Again, a fine work that uncovers the tawdry veneer that obscures real history! Thank you for helping us better understand the long misunderstood & maligned woman who broke the bar against female English monarchs!

  10. I have always felt sorry for her. The stress that she lived under 24/7, rejection of her father and separation from her mother, it’s a wonder she lived as long as she did. A political marriage and pressure to have an heir made the perfect setting for the false pregnancies. I for one would not have wanted to live during that time.
