What causes sudden numbness throughout the body accompanied by palpitations?

Sudden numbness throughout the body accompanied by palpitations may be caused by physiological factors or pathological conditions. Physiological causes might include excessive mental stress, while pathological causes could involve hyperthyroidism, hypoglycemia, and other conditions.

I. Physiological Factors

If a patient experiences prolonged mental stress or stays up late frequently, it may lead to insufficient blood supply in the body, resulting in chest tightness, as well as sensations of full-body numbness and palpitations. These symptoms usually improve once mental stress is relieved.

II. Pathological Factors

1. Hyperthyroidism

This condition is primarily characterized by increased metabolic rate and overactivity of the sympathetic nervous system. Patients typically experience symptoms such as palpitations and neck swelling. Some individuals may also develop chest tightness and generalized numbness. Treatment may include medications such as propylthiouracil tablets or methimazole tablets, taken as directed by a physician.

2. Hypoglycemia

Hypoglycemia leads to inadequate energy supply to the brain, causing dizziness, rapid heartbeat, and fast breathing. Additionally, due to insufficient glucose supply, muscle cell excitability may decrease, leading to numbness in the limbs. Symptoms generally improve promptly after timely sugar intake.

Besides the above, anemia could also be a potential cause. During treatment, patients should ensure adequate rest and maintain a balanced diet, avoiding picky eating habits.
