Regarding abdominal problems and associated ailments

Are you using the two medicines mentioned by you on your own or any doctor suggested? I advise you not to use those medicines regularly without consulting a good physician.
There are some medicines in Homeopathy also. But you should consult a qualified homoeopathy doctor for proper medicine.
Coming to Ayurveda, as mentioned by you Triphala powder is very good for indigestion and gas problems. You have to have one dose of the same, the night after your meal. It will facilitate free motion and also geas problem will come down. In addition to the above LIV 52, an ayurvedic product from Himalaya company is good for your liver function. My mother was having a problem like what you have mentioned. She used Triphala daily and then LIV 52 tablets twice daily. Now she is completely free from that problem.
A word of caution is that before using any medicine it is always better to consult a qualified physician and then use the medicines as per his directions.

I have gone through your submission and what I feel both the allopathic medicines PAN 40 and FOMOCID 40 taking in the morning and evening respectively are not healthy healthy practices. It ultimately becomes habit forming and in that situation more complications would arise in future. To combat the issues with which you are suffering, you may take up the formulations as indicated below-
1) You may take a bottle of Triphala Churna of any reputed aurvvedic pharmacy and the same might be taken to the extent of one teaspoon dissolved in the water daily in the night after your dinner for the duration as suggested by your Ayurvedic Doctor. The ingredients used for this formulation are Harad, Baheda and Amlaki pacifying Vata, Cough and Pitta Prakriti respectively signifying that this Rasayan tones up the entire body mechanism.
Within a fortnight, you could see its results.
2) If the liver function is not up to the mark, excess gas formation is seen in the stomach. Hence any Ayurvedic formulation acting on your liver could give you relief permanently without any side effects. LIV 52 contains a number of beneficial Ayurvedic ingredients which could stimulate your liver for proper functioning. The other medicines in this line are Abhyaristha, Pancharistha, Guduchi etc but before you use any one of such formulations, you need to consult a competent Vaidya.
3) However, you may take up the following remedy for your gas issues. Take a glass containing 40 ml of water and pour 15 pieces of kismis into water in night and consume the soaked kismis along with water in the morning in the empty stomach. Kismis are to chewed properly prior to ingestion. Within a fortnight, you could notice amazing results. It will not only take care of your gaseous issues but at the same time, it would strengthen your liver and take care of your anaemia if that is troubling you.
