Patients with lactose intolerance who experience nausea can consider using some medications for symptomatic treatment. For example, they can use meclozine orally or by muscle injection. They may also use medications that promote gastric motility, such as domperidone, mosapride, and itopride, to treat impaired gastric motility. Patients with lactose intolerance may also experience bloating, vomiting, abdominal pain, diarrhea, and constipation. Appropriate symptomatic treatments can be taken according to different symptoms. Lactose intolerance, if due to a secondary disease such as Crohn's disease or ulcerative colitis, requires active treatment of the primary disease. (The use of medications should be under the guidance of a professional doctor.)

Is weakly positive lactose intolerance serious?

Lactose intolerance is weakly positive, not particularly severe, and can be improved by taking oral lactase. For mild cases of lactose intolerance, symptoms can be alleviated after taking lactase. However, it is important to monitor the condition when consuming milk powder or milk. If symptoms persistently recur, it may be prudent to switch to extensively hydrolyzed milk powder or other lactose-free milk powder.

What should I do if I vomit due to lactose intolerance?

Lactose intolerance can lead to vomiting, which can be managed based on the condition by symptomatic treatment. For example, Metoclopramide can be used orally or through muscle injection to alleviate vomiting. If necessary, chlorpromazine injections can also be used for treatment. The choice of specific medications and their administration must adhere to medical advice. In addition to addressing the symptoms, it is essential to treat the primary disease causing lactose intolerance. For instance, if it is caused by ulcerative colitis, then treatment should focus on this condition. In the case of primary lactose intolerance, a lifelong avoidance of lactose-containing foods is necessary. (Medication use should be under the guidance of a physician.)

What should I do if the baby is lactose intolerant?

If the baby is lactose intolerant and does not have frequent bowel movements and it does not affect their growth and development, then no special treatment is needed. If there is frequent diarrhea and slow weight gain, then an adjustment in diet is necessary. If there is significant acute diarrhea accompanied by dehydration, we should initially rehydrate the infant either intravenously or orally to correct the dehydration. At the same time, you can start with some lactose-free formula and, after the diarrhea stops, gradually increase the amount of breast milk or other formulas based on the child's condition. Regardless of whatever food substitute is used, the overall principle is to not decrease the nutritional needs of the child. As solid foods are introduced and breast milk or cow's milk is decreased, diarrhea will gradually cease. If diarrhea does not subside, oral lactase enzyme preparations can also be provided to supplement lactase enzyme therapy.

What should I do if lactose intolerance makes me feel like vomiting?

People with lactose intolerance often feel nauseous and should avoid drinking milk. If they must drink milk, it needs to undergo special treatment first. Consuming untreated milk can lead to diarrhea in lactose-intolerant individuals, and severe cases may result in dehydration and electrolyte imbalance. Additionally, those with lactose intolerance should also check for any milk allergies or diarrhea caused by indigestion. It is essential to conduct allergen tests and, if necessary, take oral medication to regulate the digestive system.

Can lactose intolerance cause eczema?

Lactose intolerance generally does not cause eczema in patients. Lactose intolerance can be divided into primary lactase deficiency, secondary lactase deficiency, and congenital lactase deficiency. Patients with lactose intolerance mainly experience symptoms such as abdominal pain, diarrhea, nausea, vomiting, increased bowel sounds, intestinal colic, and bloating. Some patients experience reduced intestinal motility, leading to constipation, and the severity of symptoms is related to the amount of dairy products consumed. Therefore, a small number of patients can tolerate a certain amount of dairy products without experiencing significant symptoms, and the specific tolerable amount varies from person to person.
