What causes underactive thyroid?

My friend was just diagnosed with an underactive thyroid, and she's feeling very tired and low. I'm trying to learn more to support her. What typically causes someone to develop an underactive thyroid?

Underactive thyroid can be caused by a few things, but most commonly, it's an autoimmune condition where your body attacks its own thyroid gland. Sometimes it can also be a side effect of certain treatments. It's a common condition, so don't feel alone.

Beta, underactive thyroid, also called hypothyroidism, is quite common. Often it's when your own body's power gets confused and attacks the thyroid gland. Sometimes it's from not enough iodine in the food too. While doctors give medicine, some say eating coconut oil or specific herbs helps, but always ask doctor first, don't stop medicines.

My endocrinologist explained that the most common cause of underactive thyroid (hypothyroidism) is an autoimmune disease called Hashimoto's thyroiditis, where the immune system attacks the thyroid gland. Other causes include thyroid inflammation, certain medications, surgical removal of part or all of the thyroid, radiation treatment, and sometimes iodine deficiency. It's a complex condition requiring precise diagnosis.

Underactive thyroid can be caused by several factors, like an autoimmune disease (Hashimoto's thyroiditis being most common), certain medications, or even iodine deficiency. It's important not to self-diagnose. If you suspect anything, always get it checked by a doctor for proper diagnosis and management, for your own safety.

Hey, don't stress too much, underactive thyroid is super common! Mostly it's because your immune system gets confused and attacks your thyroid gland, that's Hashimoto's. Sometimes it can be from not enough iodine or even after pregnancy. But it's totally manageable with medicines, so just get it checked if you suspect anything!

Basically, underactive thyroid mostly happens because your immune system attacks your own thyroid gland, which is called Hashimoto's. Sometimes it's from iodine deficiency, or maybe medicine you took. Just get your blood test done, and if it's low, the doctor will give you medicine. No fuss, just manage it.

Underactive thyroid, or hypothyroidism, is usually due to an autoimmune condition like Hashimoto's, where your body attacks its own thyroid. It can also stem from surgical removal of the thyroid or certain medications. For working professionals, it's a chronic condition that needs consistent medication and routine blood tests, so factor that into your schedule. Don't skip doctor visits.

Namaste. An underactive thyroid often arises from an imbalance in the body's subtle energies, leading to the immune system mistakenly affecting the thyroid gland. This is commonly known as Hashimoto's. While medical treatment is essential, I have found that gentle yoga, specific pranayama, and mindful eating, under guidance, can support the body's healing journey. It's about harmony.

My son was diagnosed with hypothyroidism a few years back. The doctors explained it's an autoimmune condition for him, where his body's own system was attacking his thyroid. It's mostly not about what you eat or do, it just happens. Now he takes a daily pill, and his levels are normal. It's practical to just get tested regularly and follow the doctor's instructions.

Haan na, underactive thyroid mostly happens because your own body's cells start fighting your thyroid gland, that's Hashimoto's. Sometimes it can be due to not enough iodine too. But jo bhi ho, it's very common, ho na. Just take your medicine regularly, doc will tell.

Underactive thyroid can cause many issues if not treated, I've seen it. The most common cause is Hashimoto's, an autoimmune disease. But it can also be from radiation, surgery, or certain medicines. Don't self-diagnose or try to treat it on your own. It's really important to see a doctor and get proper diagnosis and medication to avoid complications.
