The causes of stomach discomfort vary, so whether you can drink yogurt should be analyzed according to different situations. If the upset stomach is caused by excessive secretion of stomach acid, it is not recommended to drink yogurt at this time. If the upset stomach is caused by indigestion, you can drink yogurt in moderation. If the stomach acid secretion is too much and cause stomach discomfort, this is not recommended to drink yogurt. Stomach acid and yogurt are both acidic. Drinking yogurt when stomach acid is overproduced may cause the stomach to secrete more stomach acid, which may aggravate the symptoms of an upset stomach. If you have an upset stomach due to indigestion, you can drink yogurt in moderation at this time. Some probiotics contained in yogurt can help regulate the balance of intestinal flora and promote intestinal peristalsis, potentially relieving stomach discomfort caused by indigestion. When patients have symptoms of stomach discomfort, they should go to the regular hospital in time, under the guidance of professional doctors for targeted treatment.
