I have been staying away from milk and bread because i have long suspected an intolerance to them. Today i drank a lot of milk and bread to see if i did have worse heartburn or lpr. I did notice bad heartburn and breathing issues but its hard to know if its cause by gerd in general or an intolerance... Food allergies are often quick reactions and ive heard that an intolerance can be between 30 mins to 48 hrs after ingestion...
Heres what can happen if you have a food intolerance
Food intolerance can present with symptoms affecting the skin, respiratory tract, gastrointestinal tract (GIT) either individually or in combination. On the skin may include skin rashes, urticaria (hives),angioedema, dermatitis, and eczema. Respiratory tract symptoms can include nasal congestion, sinusitis, pharyngeal irritations, asthma and an unproductive cough. GIT symptoms include mouth ulcers, abdominal cramp, nausea, gas, intermittent diarrhea, constipation, irritable bowel syndrome, and may include anaphylaxis.
