12 Muscle Twitching Causes You Should Know (Common Triggers)

Hormonal Imbalance

Hormones are chemical messengers that are essential inside the body. They instruct the organs to perform their bodily functions and vital processes, like reproduction, digestion, and metabolism. Excessive or inadequate amounts of hormones affect the overall health of the body. This fluctuation in hormones is called hormonal imbalance. 

One example of a hormone that adversely affects the muscle is the thyroid. The thyroid instructs the muscle to develop, specifically the skeletal muscles. It also regulates the contraction and regeneration of muscles. The alteration of the number of thyroid hormones in the body causes muscle twitching. Cases like hypothyroidism, or when the thyroid gland is making an insufficient amount of thyroid, worsen the muscle twitching experienced in the body. 

Another hormone involved in muscle twitching’s cortisol. Cortisol’s primary function is to regulate the body’s fats, proteins, and carbohydrates. Once the cortisol elevates its number in the body, it also increases muscle tension leading to muscle twitching. The altering of hormones, such as cortisol and thyroid, is one of the leading causes of muscle twitching.
