Why would you get shaky but never feel hungry?

Shaking and a loss of appetite are common symptoms of hypoglycemia, which is a condition that occurs when the blood sugar level drops too low. Hypoglycemia can be caused by several factors including: Not eating enough carbohydrates which are the body's main source of energy. Taking too much insulin or other medications that lower blood sugar. Drinking too much alcohol which can interfere with the liver's ability to produce glucose. Having certain medical conditions such as diabetes, liver disease, or kidney disease. If you are experiencing shaking and a loss of appetite it's important to see a doctor to rule out any underlying medical conditions and to receive proper treatment.
