The thyroid gland works by producing hormones called thyroxine, which help regulate energy levels and control metabolism. When thyroid hormones do not function effectively, the metabolism is disrupted, making your body feel tired.

Due to adrenal insufficiency

Adrenal insufficiency is a less common disease than thyroid insufficiency, but it also causes fatigue. This is a condition when the adrenal glands do not function properly. In addition to fatigue, adrenal insufficiency can also cause weight loss, headaches, abdominal pain, diarrhea, and increased skin pigmentation.
