13. Weakness Accompanied by Muscle Aches and Pains (Hypothyroidism)
Low levels of thyroid hormone cause a decrease in the body’s ability to produce energy from food, forcing it to seek other sources within itself and use those to make energy. This process known as catabolism, involves the breakdown of tissues such as muscle to convert it to energy. This results in a marked decrease in muscle strength and is often accompanied by muscle pain and cramping.
