A little while after I started to drink protein shakes get stomach pains but used the bathroom it stoped so had another shake this happened again do have a ulcer?

You should consult with a doctor promptly to accurately determine the cause of your abdominal pain. Self-diagnosis can be misleading and potentially harmful. Your doctor will be able to run the appropriate tests and provide the best advice for managing your symptoms.

Protein shakes can sometimes cause stomach pain and diarrhoea in some individuals, especially if consumed on an empty stomach or if you are not accustomed to consuming a high protein diet. However, if you are experiencing persistent or intense abdominal pain, and it resolves after having a bowel movement, it could indicate an underlying medical condition such as an ulcer.

Here are a few possible causes of stomach pain after drinking protein shakes:

1. Lactose Intolerance: If you are lactose intolerant, consuming protein shakes made with milk or dairy-based protein powders can cause digestive issues such as bloating, gas, and abdominal pain.

2. Irritable Bowel Syndrome (IBS): Individuals with IBS may experience stomach pain, diarrhoea, and constipation after consuming certain foods, including protein shakes.

3. Inflammatory Bowel Disease (IBD): Crohn's disease and ulcerative colitis are two types of IBD that can cause abdominal pain, diarrhoea, and other digestive symptoms.

4. Food Intolerance or Allergies: Some individuals may have food intolerances or allergies to specific ingredients found in protein shakes, such as whey, soy, or nuts, which can cause stomach pain.

5. Overconsumption of Protein: Consuming too much protein, beyond what your body requires, can lead to digestive discomfort, including stomach pain.

6. Ulcers: Peptic ulcers, which are sores in the lining of the stomach or small intestine, can also cause abdominal pain, especially after eating or drinking certain foods and beverages.

It is essential to consult with a medical professional to determine the exact cause of your stomach pain and rule out any potentially serious underlying conditions. Your doctor may recommend dietary modifications, medications, or further tests to manage your symptoms effectively. Self-diagnosis and treatment without proper medical advice can be risky, so seeking professional help is crucial for your well-being.
