Dad is 53 years old this year. He has been upset with his stomach for five years, especially now he has been suffering from stomachache, bloating and diarrhea. I don't know what to do. He doesn't want to have a colonoscopy. Older people, because they don't pay attention to their health at ordinary times, stomach problems will become more and more serious. Gastropathy: Generally speaking, bad living habits and mental stress reduce the digestion and absorption function of the stomach, resulting in belching, pantothenic acid, stomachache, heartburn, burning sensation and other symptoms. Generally, the treatment of stomach diseases is divided into three parts and seven parts. People with stomach problems should pay attention to the following aspects: 1. Cooperate with the doctor to suit the right medicine and choose the stomach medicine that suits you (after eating it, pay attention to observe what medicine is effective and not expensive). 2, diet: eat less and eat more, chew slowly. Eat more digestible, soft fish, meat, fungi, fresh vegetables, fruits and other foods, and do not eat high-fat, cold, hard, spicy and other irritating foods. In particular, people with abdominal distension should eat less gas-producing foods (such as sweets, potatoes and beans). Exercise: Exercise properly according to your age and physical strength to help gastrointestinal peristalsis and promote digestion and absorption. 4. Spirit: Don't be overworked and tired in work and life, and ensure a good sleep. Don't be irritable, pay attention to adjust your mentality in time (being good at communicating with people and talking can release you), and often participating in some group or entertainment activities can relax your spirit and improve the digestion and absorption function of the stomach. 5, pay attention to keep warm, the weather is cold and warm, you should add clothes in time, especially pay attention to keep your stomach warm, don't catch cold. If you want to completely treat stomach diseases, you must persist for a long time and gradually enhance your resistance and immunity. Most of them will achieve satisfactory results.
