Appetite loss, low digestion

Hello Sir/Madam,

I am not feeling hungry from the last two weeks. Neither am I feeling physically weak.
The following are my observations:

1) I feel like I am having lot of gas in my stomach and frequent burping is there.
2) The stool is oily from past one week or so.
3) If I sit at a place for longer time, then there is severe bloating.
4) I had loose motions around 6 months back which lasted for more than a week. It seemed to be allergy to diary products because allopathy doctor suggested it when I told him that stool smelled like spoiled curd.
5) I have had sinusitis for years. When I am having nasal discharge, regularly the mucus through the mouth goes into the stomach. This decreases my digestive capacity. I feel exhausted due to frequent sneezing and hence loss of energy.
6) I regularly skip breakfast due to dynamic timings at work.

I probably have weak digestive fire from a couple of years because I cannot eat much food compared to people of my age.

The problems become a little bit less with good exercise, but comes back again after eating food.

Following are my details:
Age: 29
Gender: Male
Marital Status: Married
Profession: Computer Engineer
Weight: 68 Kg
Height: 5'8"
Health problems: Sinusitis(comes almost once every 6 months),
minor asthma wheezing controlled currently using nebulization and levosalbutamol inhaler.

Kindly suggest me what I have to do.

Thanks & Regards
