Eating too much pineapple triggers stomach pain, which can be relieved by drinking light salt water or milk or treated with omeprazole or aluminum hydroxide gel. The acidity of pineapple is relatively strong, and when eaten in an empty stomach state, the acidity can directly cause irritation to the gastric mucosa, thus inducing stomach pain. In the event of stomach pain, you can properly drink a glass of light salt water or milk, not only to relieve the stimulation caused by acidic substances on the gastric mucosa, but also to protect the gastric mucosa, relieve stomach cramps and reduce pain. Some people eat too much stomach pain is caused by the presence of inflammation and ulcerated surface on the gastric mucosa. When these people eat pineapple, the secretion of gastric acid can cause irritation to the gastric mucosa, thus inducing a painful sensation in the stomach, which needs to be treated with drugs that reduce the secretion of gastric acid, such as omeprazole. Aluminum hydroxide gel not only reduces the concentration of stomach acid, but also protects the gastric mucosa. Aluminum hydroxide gel contains a part of belladonna, which can achieve the effect of antispasmodic and pain relief.
