Bollywood actor Arjun Kapoor recently revealed that he has an autoimmune disorder called Hashimoto’s Thyroiditis, which he felt, contributed to gaining body weight.
Hashimoto’s Thyroiditis is a condition in which the immune system mistakenly targets the thyroid gland, leading to inflammation, damage, and, often, hypothyroidism.
While Hashimoto’s leads to an underactive thyroid (hypothyroidism), other conditions like Graves’ disease cause an overactive thyroid (hyperthyroidism).
Hypothyroidism itself can have various causes, but in Hashimoto’s, it results from an immune attack on the thyroid, which makes it unique among thyroid disorders.
