Is it easy to have diarrhea during weight loss

During weight loss, it may be easy to experience diarrhea, which is usually related to changes in dietary structure, imbalance of gut microbiota, and in rare cases, may be caused by disease factors. Suddenly reducing high-fat and high calorie intake can lead to a decrease in bile secretion, affecting fat digestion and absorption. Underdigested food can stimulate intestinal peristalsis and accelerate. When some people increase their dietary fiber intake, their intestinal tolerance to crude fiber may be insufficient, which may lead to an increase in transient bowel movements. Some sugar substitute food additives such as erythritol and maltitol may alter intestinal osmotic pressure, and some people may experience diarrhea symptoms after consuming them.

In rare cases, it is necessary to be alert to pathological diarrhea, such as in patients with chronic enteritis who may experience worsening symptoms during dietary adjustments. Elevated basal metabolic rate in patients with hyperthyroidism may be accompanied by abnormal bowel movements, and diarrhea symptoms may be more pronounced in this population during dietary control. Individuals with lactose intolerance who suddenly increase their intake of low-fat dairy products may also experience diarrhea attacks.

It is recommended to gradually increase dietary fiber when adjusting the diet structure to avoid sudden large amounts of coarse grains replacing fine staple foods. When choosing sugar substitute products, attention should be paid to the ingredient list, and the intake should be controlled when trying new meal substitutes for the first time. If diarrhea is accompanied by fever, bloody stools, or lasts for more than 3 days, medical attention should be sought promptly to screen for organic diseases. In daily life, probiotics can be supplemented in moderation to regulate the gut microbiota, and cooking methods mainly involve steaming to reduce oil irritation.
