The symptoms of bloating in the afternoon may be related to stomach diseases, intestinal diseases or gastrointestinal dysfunction, intestinal flora imbalance, etc. If the symptoms are mild flatulence, you can promote intestinal peristalsis and relieve flatulence by means of manual massage. You should eat more fruits such as grapefruit, pear and dragon fruit, eat foods with high fiber content and coarse grains, and try to eat less soy products and other foods that are more likely to produce gas. Be careful not to eat cold foods, fried foods, hotpot-type foods and irritating foods. If you have symptoms of stomach bloating, acidity and hiccups, you can take medications such as omeprazole and martinoline. If there is an increase in the frequency of stools, unformed stools, undigested food residues in the stools, and hyperactive bowel sounds, you can take medications such as pepsin, lactase, and bifidobacterium trituberculatum.
