Hi, whenever I have ghee, buttermilk, or curd, it seems to trigger a cough and cold. Im wondering if its related to my immunity or something else. Could it be lactose intolerance? Should I consider any specific diagnostic tests to confirm? Please suggest a remedy or advice.

Experiencing cough and cold after consuming buttermilk and curd may be related to several factors, including lactose intolerance, dairy protein allergy, or an immune response.Possible Causes1. Lactose intolerance: Difficulty digesting lactose, a sugar found in milk, can lead to respiratory symptoms like coughing and congestion.2. Dairy protein allergy: Allergy to milk proteins like casein or whey can trigger an immune response, resulting in respiratory symptoms.3. Immune system response: Some people may experience an immune response to dairy products, leading to inflammation and respiratory symptoms.Diagnostic Tests1. Lactose tolerance test: Measures the body's ability to digest lactose.2. Elimination diet: Remove dairy products from your diet for 2-4 weeks to assess symptom improvement.3. Skin prick test or blood tests: To check for dairy protein allergies.4. IgE antibody test: To assess immune system response to dairy products.Remedies1. Lactose-free or low-lactose dairy products: Try lactose-free milk, buttermilk, or curd.2. Non-dairy alternatives: Explore alternatives like almond milk, soy milk, or coconut-based products.3. Probiotics: Add probiotics to your diet to support gut health and potentially improve lactose tolerance.4. Avoid triggers: If you identify dairy products as triggers, avoid them or reduce consumption.
