If a cause of hyperhidrosis (excessive sweating) can be identified, it’s known as secondary hyperhidrosis. Secondary hyperhidrosis can have a number of different triggers, including: pregnancy; menopause; anxiety; low blood sugar; an overactive thyroid gland; obesity; certain medications – including some antidepressants; being drunk or “high” on drugs, or withdrawing from alcohol or drugs if you have become addicted to them; some infections, such as tuberculosis and HI; Parkinson’s disease; disorders of the blood cells or bone marrow etc. Secondary hyperhidrosis often starts more suddenly than primary hyperhidrosis and tends to affect the whole body.
