### input:
I think i might be lack toast and tolerant, but i m not too sure. I ve noticed that recently for about a few weeks, whenever i would have milk, milkshakes, or mac and cheese, i would get bad stomach pains. Sometimes the pains would last about 30 minutes, but at other times diarrhea comes with it. For example yesterday, i had a milkshake, and when i got home, my stomach hurt badly. And this morning i ve had alot of gas to go with it. I m not sure if that s what goes with it, but could you tell me if what i m saying sounds like i have it, and/or if i should go get a test?

### output:

Hello. Thank you for asking at Chat Doctor. I went through your history and would like to know more details about you like - What is your age? Have you had any other allergies? Do you take any other medicines regularly/frequently? Did you have diarrhea or any other illness recently? from your history, I would like to make following suggestions to you:1. Were I treating you, I would suggest you stool examination and specific IGE for milk proteins. These tests may be helpful to identify whether you have milk intolerance or milk allergy or anything else.2. I would suggest you to avoid milk and milk products for at least 4-6 weeks. If you feel significant improvement, personally I would suggest you to continue avoidance of milk and milk products for at least 3 months.3. I would suggest you to take probiotics like Saccharomyces bollards, Lactobacillus, etc., which may improve your digestion of milk proteins. Hope above suggestions will be helpful to you. Should you have any further query, please feel free to ask at Chat Doctor. Wish you a quick recovery and the best of the health. Thank you & Regards.
