Claims that The Mona Lisa suffered from severe hypothyroidism and that her enigmatic smile was due to a muscle-brain disorder that is not true, an expert claims.
Dr. Michael Yafi from the University of Texas said there was probably nothing wrong with the woman sitting in front of the portrait.
He says she would have shown more visible symptoms if she suffered from this medical problem.
The woman might not even have been able to sit in front of the portrait if she suffered the associated symptoms of muscle weakness.
The discoloration of the painting was the most likely explanation behind her yellow skin color and her asymmetrical smile is nothing more than her enigma.

In recent years, rheumatologists and endocrinologists investigating the famous painting by Leonardo da Vinci have suggested that the woman who sat in front of the portrait hundreds of years ago suffered skin lesions and swelling as a result of lipid disorder and heart disease.
But Dr. Michael Yafi of the Pediatric Endocrinology Department at the University of Texas noted in his latest analysis that the Mona Lisa suffered from an underactive thyroid gland that gave her an enlarged neck and made her facial muscles weak, unfounded.
In a written statement, Dr. Yafi said: & # 39; I felt personally responsible for defending the & # 39; Mona Lisa & # 39; and the fascinating lady who portrays the painting.
& # 39; She has inspired thousands of people over the past centuries. I couldn't make the public think that she had hypothyroidism, while I think it was her euthyroid, which means that her thyroid was normal.
& # 39; Artists often portrayed what they saw in society. Sculptures from ancient Egyptian and Egyptian civilizations registered endemic crop tools in areas with an environmental iodine deficiency, such as the Tuscany region, where [The Mona Lisa] lived.
But the doctor noted that the babysitter would not even have been able to sit in front of a painting if she was suffering from the kind of muscle weakness and slowdown alleged in the past.
The pediatric endocrinologist from Houston attributed other symptoms that have been mentioned, such as her yellow skin, simply because of the & # 39; discoloration due to the age of the artwork & # 39; and called medical diagnosis based on these subtle traits & # 39; risky & # 39 ;.
He did mention, however, that the Mona Lisa who was pregnant before the portrait could have had peripartum thyroiditis, a temporary inflammation of the thyroid gland after pregnancy.
This corresponds to other medical opinions that were previously made by.

Little is known about the life of Lisa Gherardini, the Italian noblewoman who is reportedly the subject of da Vinci's Mona Lisa.
Her hands in the painting show signs of swelling and it seems that her hair is thinning, it was claimed.
Previous medical experts have also pointed to her skin color and what, according to some, might be a goiter – what would appear to be an enlarged neck opening – as symptoms of various conditions.
Hypothyroidism, in which the thyroid gland does not produce sufficient amounts of key hormones, can cause thinning hair, yellow skin and goiter.
Dr. Mandeep R. Mehra, medical director of the Heart & Vascular Center of Brigham and the Women's & # 39; s Hospital, said earlier that hypothyroidism could explain these traits.
Mehra and Hilary Campbell of the University of California Santa Barbara wrote in the Mayo Clinic Proceedings Journal: & # 39; The riddle of the Mona Lisa can be solved by a simple medical diagnosis of a hypothyroidism-related disease.
& # 39; In many ways it is the allure of the imperfections of the disease that gives this masterpiece its mysterious reality and charm. & # 39;
Although previous analyzes have suggested that other conditions may play a role, Dr. says. Mehra that heart disease and lipid disorder are unlikely, since she lived to the age of 63.
With these disorders, she would probably have died much younger, given the medical limitations of the 16th century.
The inflammation of the thyroid gland after pregnancy was according to Dr. Mehra also a possibility at that time.
Diet in Italy during this period is also known to lack iodine, which could explain the goiter or swollen thyroid gland, said Dr. Mehra.
& # 39; She may have suffered from a subclinical presentation of peripartum thyroiditis, with an early manifestation of hyperthyroidism eventually occurring in a chronic phase of hypothyroidism, & # 39; the researchers wrote.
& # 39; This, in combination with living conditions and the iodine-deficient diet of this period in the Florentine region, would typically have led to the secondary manifestations of underlying hypothyroidism. & # 39;
