Understanding Thyroid Problems in India
Share
Introduction
Thyroid disorders are among the most common hormone-related diseases in the world. In India, around 42 million people are believed to suffer from some form of thyroid disease. These issues can affect people of all ages and often go unnoticed until symptoms become serious. Early diagnosis and treatment can make a big difference.
Common Thyroid Problems in India
There are several types of thyroid disorders. The most common ones in India include:
- Hypothyroidism – when the thyroid gland doesn’t make enough hormones
- Hyperthyroidism – when the thyroid makes too many hormones
- Goiter and iodine deficiency disorders – swelling in the neck caused by lack of iodine
- Hashimoto’s thyroiditis – an autoimmune condition
- Thyroid cancer
Hypothyroidism
This is the most common thyroid disorder in India. It can even affect newborn babies, which is dangerous because it can lead to brain damage if not treated early. In adults, a study in Cochin found that 3.9% of people had hypothyroidism and 9.4% had mild, or "subclinical," hypothyroidism. Women were affected more than men.
Hyperthyroidism
This is less common but still important. In the same Cochin study, 2.9% of people had either subclinical or full hyperthyroidism. Some had visible neck swelling (goiter), and many tested positive for thyroid antibodies, which means the immune system was attacking the thyroid.
Goiter and Iodine Deficiency
Goiter is a swelling in the neck due to an enlarged thyroid. It’s often linked to iodine deficiency, though autoimmune conditions can also cause it. Thanks to salt iodization programs in India, iodine deficiency has decreased. But some areas still report high goiter rates, showing that other factors like diet and environment may also play a role.
Hashimoto’s Thyroiditis
This is an autoimmune disease where the immune system attacks the thyroid. A large study found that about 7.5% of girls with goiter had this condition. It can cause both visible swelling and hormone problems like hypothyroidism.
Thyroid Cancer
Though less common than other conditions, thyroid cancer is being reported more frequently. Data from the Indian Cancer Registry showed that certain cities, like Thiruvananthapuram, had higher rates. Women were more affected than men, and most cases were of a type called "papillary carcinoma," which usually grows slowly.
What’s Being Done?
India has made big improvements, like promoting iodized salt and conducting nationwide studies on thyroid health. Researchers are also working to find better reference levels for thyroid hormones during pregnancy and childhood, to help diagnose issues early.
Conclusion
Thyroid problems are a major health concern in India. They affect millions, especially women and children. The good news is that they can be managed well if caught early. More awareness, regular check-ups, and continued research will help reduce the burden of these diseases in the years to come.
