Hi,
Thanks for choosing HealthcareMagic for your query,
Have noted all your details,

Indigestion is the most common cause of excessive gas formation in stomach.Improper digestion leads to fermentation of food in stomach leading to production of large amount of gases.

There are usually two main sources of gas in digestive tract-
1)swallowed air-Air swallowing, is a common cause of gas in the stomach. Eating or drinking rapidly, chewing gum, smoking, or wearing loose dentures can cause some you to take in more air.
2)As already told above breakdown of Undigested Foods :
The body does not digest and absorb some carbohydrates like sugar, starch, and fiber as our small intestine lack enzymes to digest them.
This undigested food then passes from the small intestine into the large intestine, where normal, harmless bacteria break down the food, producing hydrogen, carbon dioxide etc..

As you have to take Miralax for bowel moment daily it means that you are having constipation.Gelatinous stool can be because of presence of extra mucous in stool.Secretion of mucous is a natural phenomenon,However when you are constipated our intestine try to secrete more mucous to provide extra lubrication to assist stools to pass through them easily,Blood in stool can be due to erosion of Rectal mucosa due to constipation.Straining or passing hard stool can erode mucosa layer causing Mild bleeding.

Test advice
Proctoscopic examination of rectum to rule out Hemorrhoids as possible source of bleed.
Stool routine and microscopic examination(to rule out bacterial infection).
Colnoscopy should be done to rule out possibility of imflammatory bowel disease.

Suggestion

Start taking Neksium 40mg twice daily to provide you immediate symptomatic relief in gas.

Miralax should be taken 15ml while going to bed and not in morning for maximum benefits. Disssolve it in a cup water and drink it.

Take a probiotic daily,It aids in proper digestion of food.
Cut down your fibres intake.
Exercise daily for 30 minutes.
Try to restrict carbohydrates they are usually responsible for gas formation.
Digestive enzymes, such as lactase supplements, actually help digest carbohydrates and may allow people to eat foods that normally cause gas.
Avoid food which cause excessive formation of gas.
Food to be avoided-
Beans,vegetables such as artichokes, asparagus, broccoli, cabbage, Brussels sprouts, cauliflower, cucumbers, green peppers, onions, radishes, celery, carrots,they form a lot of gas.
Fruits such as apples, peaches, raisins, bananas, apricots, prune juice, pears
Whole grains and XXXXXXX
Carbonated drinks and alcohol.
Dairy products.
Try to avoid swallowing excessive air while eating.

Detailed Answer:
Hi again,

I would recommend you to take Culturelle Probiotic thrice daily.

In trials it has been seen that esomeprazole 40 mg provides more effective acid control than twice the standard dose of omeprazole.Though both belong to same group yet results with esomeprazole were significantly better,And remember to take it empty stomach for maximum benefits.

Regards.
