Long-term skipping breakfast is easy to cause cholecystitis, gastritis, hypoglycemia and other diseases. 1. Cholecystitis: Bile is mainly excreted through the liver and stored in the gallbladder. Eating breakfast can promote the excretion of bile in the gallbladder, and not eating breakfast for a long time will reduce the excretion of bile, leading to the accumulation of bile in the gallbladder, the formation of gallbladder stones, which will lead to the occurrence of cholecystitis. 2. Gastritis: patients who do not eat breakfast for a long time will easily cause the stomach to be empty for a long time, and the gastric acid secretion will be too much, which will directly stimulate the gastric mucosa, leading to ulceration and erosion of the gastric mucosa, causing gastritis and gastric ulcer. 3. Hypoglycemia: patients do not eat breakfast for a long time, resulting in insufficient supply of energy in the body, resulting in hypoglycemia such as dizziness, headache, fatigue and so on. It is recommended that patients should eat on time to avoid the adverse consequences.
