Why Women Are More Prone to Hypothyroidism: Find Out From The Expert

Hypothyroidism is an endocrine disorder in which the thyroid gland fails to produce sufficient thyroid hormones. It is seen five to eight times more often in women than in men, a trend confirmed by most epidemiological studies. This strong female predominance is believed to result from a mix of genetic, biological, hormonal, and lifestyle factors.

We spoke to Dr Phulrenu Chauhan, Endocrinology Consultant, P.D. Hinduja Hospital and Medical Research Centre, Khar, Mumbai, to understand why hypothyroidism affects women far more than men.

Role of Autoimmune Disorders

The most common cause of hypothyroidism on a global scale is an autoimmune disorder called Hashimoto's thyroiditis. With this particular disorder, the immune system mistakenly attacks the thyroid gland, causing it to lose its working capacity over time.

"As a general rule, women tend to be more susceptible to autoimmune disorders since their immune systems are typically more active and reactive. On the bright side, it means that they are better protected against infections, but on the other hand, it raises the risk of autoimmune diseases such as thyroid disorders," explained Dr Chauhan.

Hormonal Changes Across a Woman's Life

Hormonal fluctuations play a major role in thyroid health. Key life stages such as puberty, pregnancy, and menopause involve significant changes in estrogen and progesterone levels, which are closely linked to thyroid function.

"During pregnancy, the thyroid has to work almost twice as hard to meet the metabolic demands of both the mother and the developing foetus. Such overexertion may at times be the reason why a hidden thyroid problem shows up, or an already existing one gets worse," said Dr Chauhan.

Postpartum Period: A Vulnerable Phase

The time after giving birth is also a very risky one. "Some women can develop postpartum thyroiditis, a condition characterised by the inflammation of the thyroid gland that arises immediately after giving birth. In most cases, however, the condition resolves itself without going into permanent hypothyroidism. It is observed that women with a personal or family history of thyroid disease are especially at risk during this phase," added Dr Chauhan.

Genetic Predisposition

Genetics further contributes to a woman's higher susceptibility. Thyroid disorders often run in families. Women with close relatives who have hypothyroidism or other autoimmune conditions are significantly more likely to develop the disease themselves.

Lifestyle and Nutritional Factors

Lifestyle and nutritional factors also influence thyroid health. Women are more prone to iron deficiency due to menstruation, and inadequate iron levels can interfere with thyroid hormone production. "Similarly, iodine deficiency, a key nutrient required for thyroid function, can increase the risk of hypothyroidism. Chronic physical or emotional stress may also disrupt hormonal balance and negatively affect the thyroid gland," said Dr Chauhan.

Why Hypothyroidism Often Goes Undiagnosed

Diagnosing hypothyroidism in women can be challenging because symptoms are often mild and nonspecific. Fatigue, weight gain, hair fall, irregular periods, dry skin, and mood changes are frequently dismissed as stress, ageing, or lifestyle-related issues.

As a result, many women are diagnosed late, after living with untreated symptoms for a long time.

The Importance of Awareness and Early Care

Dr Chauhan concluded, "Awareness is therefore crucial. Women must be vigilant about symptoms that persist, keep up with regular health check-ups, and get medical evaluation whenever necessary, particularly if they have a family history of thyroid disease. On the bright side, hypothyroidism is a condition that can be easily managed. If diagnosed in time and provided with the right treatment under medical supervision, the majority of women can enjoy a healthy, energetic, and fulfilling life."
