What Happens to Your Body When You Drink Milk for Heartburn Relief

Although milk can help relieve some cases of heartburn, it doesn’t work for everyone.

Milk contains calcium, which can temporarily neutralize stomach acid and quickly relieve heartburn symptoms. Calcium carbonate, a common form of calcium, is the main ingredient in many over-the-counter antacids.

Milk can coat your esophagus, creating a protective layer between the sensitive lining of your esophagus and the acidic contents of your stomach.

The cool temperature of cold milk can also soothe the burning sensation you feel in your throat and chest.

Some research suggests that getting more protein in your diet, such as having a protein-rich snack in the evening, may reduce the risk of gastroesophageal reflux disease (GERD) and heartburn.

The same study found that small amounts of fat could also have a protective effect. Milk contains both, suggesting it may provide some short-term relief and reduce the risk of future episodes.

The soothing effect of milk does not last long. Once your body starts digesting the fats and proteins in milk, it can trigger the production of stomach acid, leading to heartburn.

If you are lactose intolerant (your body has trouble digesting the natural sugar found in milk), drinking milk can cause bloating, cramps, gas, and diarrhea. These symptoms can add to your discomfort on top of existing heartburn.

If you want to avoid dairy or are looking for alternatives, several plant-based milks can provide temporary relief from heartburn:

• Almond milk: This low-fat option is slightly more alkaline (basic or non-acidic) than cow’s milk. Almond milk can help neutralize stomach acid without triggering additional acid production. Choose unsweetened varieties to avoid added sugars, which can make symptoms worse.
• Oat milk: Creamy, low in fat and high in fiber, oat milk can provide soothing relief from the burning sensation in your throat and chest.
• Soy milk: This high-protein option offers similar benefits to cow’s milk but with less fat. Fermented soy products, in particular, are associated with a reduction in acid reflux symptoms. Choose unsweetened versions, as added sugars and flavorings can sometimes trigger heartburn.

Although dairy and non-dairy milks can be gentle options for occasional heartburn, they are not a substitute for medical care. If you suffer from frequent heartburn or GERD, talk to a doctor about lifestyle changes or treatments that can provide lasting relief.
