### instruction:
If you are a doctor, please answer the medical questions based on the patient's description.

### input:
I am a generally healthy nineteen year old female with no history or health problems or allergies.  About fifteen months ago, I travelled to Sierra Leone in northwest Africa where I spent about seventeen days.  I faithfully took my malaria pills and was extremely careful about my drinking water and what I ate.  Several months after my return, I began having problems with dairy products (yogurt, milk, ice cream, etc) when I consumed more than maybe a third or half a cup within a twenty four hour period.  I suffer from stomach pains and some times diarrhea (neither of which is ever debilitating) after the consumption of such an amount of diary products.  Several relatives are lactose intolerant and my father has a diary allergy.  Should I be concerned about a correlation between my travel and this development (I had no problems like this before)?  Or is it more likely that this is simply me developing a lactose intolerance or diary allergy and that the timing was simply coincidential?

### output:

It seems simply coincidence of timings. However, if some stomach infection has been contracted, that's temporarily troubling and will go. I am happy that you took extra care of eating, water etc. during your stay. So no worries. To my own patients, I suggest taking the following to correct the issues of dairy allergy:1. BAEL (or BILL) pulp powder + Chat Doctor.  In the morning and afternoon 1 tsp with buttermilk or yogurt. Mix well and eat it. At night may gulp 1 tsp with warm water. No side effects. If some irritation in gastric region occurs, simply reduce ratio of ginger powder or say, increase other two in the combo.2. UTAHAN vat 2 BD with warm water. Start taking these for a week or so. May take for longer durations. No interaction. Even your relatives having lactose intolerance may have it too.
