What happens if lactose intolerant children eat dairy?

When lactose intolerant children consume dairy products, they experience various symptoms due to their body's inability to digest the sugar (lactose) in milk and other dairy products. These symptoms can include:

1. Abdominal Pain and Cramping: Lactose intolerance leads to difficulty in digesting lactose, which can result in abdominal pain and discomfort. The pain is often felt in the lower abdomen and may be accompanied by bloating.

2. Diarrhea: Undigested lactose in the intestines draws water into the colon, leading to loose, watery stools. Diarrhea can cause dehydration if not managed properly.

3. Gas and Bloating: Bacteria in the large intestine ferment the undigested lactose, producing gas. This gas build-up can cause excessive flatulence and bloating.

4. Nausea and Vomiting: In some cases, lactose intolerance may induce nausea and vomiting due to the body's reaction to undigested lactose.

5. Rumbling and Noises in the Stomach: The fermentation process caused by bacteria can produce rumbling and gurgling sounds in the stomach.

6. Acid Reflux and Heartburn: Lactose intolerance can contribute to acid reflux and heartburn due to the increased production of stomach acid.

7. Fatigue and Weakness: Prolonged digestive issues and nutrient malabsorption can lead to fatigue and overall weakness.

If lactose intolerance is suspected in a child, it's essential to consult a healthcare provider for proper diagnosis, guidance on dietary modifications, and if necessary, the recommendation of lactose-free or reduced-lactose dairy alternatives.
