Lactose Intolerance vs. Indigestion: Understanding the Differences and Treatments

May 1, 2025

AdobeStock_1352533687-1Many people experience digestive discomfort, but distinguishing between lactose intolerance and indigestion can be challenging. Though both can cause similar symptoms, they stem from different underlying issues and require different approaches for relief. Understanding the root cause of your symptoms is important for managing your digestive health effectively.

What Is Lactose Intolerance?

Lactose intolerance is a digestive issue where the body has difficulty digesting lactose, a sugar found in milk and dairy products. This occurs due to a deficiency in lactase, an enzyme that breaks down lactose in the small intestine. Without enough lactase, lactose remains undigested and can lead to bloating, cramps, gas, and diarrhea, typically within 30 minutes to two hours after consuming dairy.

What Is Indigestion?

Indigestion, also known as an upset stomach, is a discomfort or burning sensation in the upper abdomen. It is often accompanied by bloating, nausea, belching, or even vomiting. Indigestion can occur after overeating, eating too quickly, consuming high-fat foods, or even when stressed. Unlike lactose intolerance, indigestion is not caused by an enzyme deficiency but rather by various factors like overeating, acid reflux, or a sensitive stomach.

How to Differentiate Between Lactose Intolerance and Indigestion

Although both conditions can lead to abdominal discomfort, the key difference lies in the cause. If your symptoms occur consistently after consuming dairy products, lactose intolerance might be to blame. On the other hand, indigestion tends to be more situational and can happen after eating certain foods or during stressful moments. If you’re unsure which condition is causing your discomfort, a visit to a primary care physician can help provide clarity.

How Are Lactose Intolerance and Indigestion Treated?

Both lactose intolerance and indigestion can be managed with lifestyle changes, but the treatments differ.

Lactose Intolerance Treatments:

  • Avoid Dairy or Choose Lactose-Free Products: If your symptoms are mild, eliminating or reducing dairy from your diet can be an effective way to prevent discomfort.

  • Lactase Supplements: For those who want to continue eating dairy, lactase enzyme supplements can help break down lactose, making it easier to digest.

  • Read Labels: Since lactose is found in many prepared foods, reading labels carefully can help avoid hidden sources of lactose.

 

Indigestion Treatments:

  • Avoid Trigger Foods: Avoiding greasy or spicy foods and staying mindful of portion sizes can help reduce the occurrence of indigestion.
  • Antacids or Over-the-counter Medications: Medications such as antacids can provide quick relief by neutralizing stomach acid and reducing discomfort.
  • Manage Stress: Stress can play a significant role in indigestion. Practices like yoga, meditation, or simply taking time to relax can help manage symptoms.
