What causes panic attacks and hand tremors when you’re hungry?

Panic and trembling hands when hungry may be a hypoglycemic reaction, but it does not exclude hyperthyroidism, anemia and other diseases.
1. hypoglycemic reaction: when there is a huge amount of exercise, eating too little, excessive glucose-lowering drugs, etc., blood glucose levels rapidly reduced, the lack of glucose oxidation of tissue cells for energy synthesis, reflex stimulation of sympathetic nerve excitation, so the heart will be panicky and hands trembling, in addition to sweating, dizziness, ringing in the ears, fatigue and other symptoms.
2. Hyperthyroidism: hungry panic attacks do not exclude themselves from hyperthyroidism, because hyperthyroidism patients increase the basal metabolic rate, resulting in rapid glucose consumption, easy to hypoglycemia, in addition to the role of thyroid hormones in the heart will also cause panic attacks.
3. anemia: severe anemia, due to tissue cell ischemia and hypoxia, heartbeat reflexively accelerated to increase the tissue blood supply, so it will be panic attack.
Hungry panic attacks are likely to be related to a variety of factors, and it is recommended that you seek medical advice to clarify the diagnosis.
