Detailed Answer:
Hello XXXX, Welcome to HCM,
I've gone through your query and understand your concern,

Most of those symptoms do appear due to acid-peptic disease (gastric problems), since you don't have any more of Ranitidine, and it's still not showed much effectiveness, so you need to start taking a PPI medication (antacid) i.e. Cap OMEPRAZOLE (Prilosec) 20mg, Twice daily in empty stomach (15-20 min before breakfast and before dinner), continue it for at least next 15 days and observe how you stay (it's mostly available over the counter only, so you shouldn't have any problem obtaining, however in some places it's prescription based, so please check with your pharmacy and if needed, please obtain it from your local physician)..

Please stay well hydrated by drinking a lot of water (it's extremely important to avoid the hard consistency of the stool, another cause for bloating and gas production), have plenty of fresh fruits, and include fresh green leafy vegetables and salads in your daily diet.

Medicine alone won't be sufficient to resolve the gastric problems, please avoid junk/ deep fried/ spicy foods for the time being..have simple home cooked meals.. avoid soda/smoking/alcohol (if you do)..

Eat in small portion but frequent meals instead of any large portion meals, try to chew the foods properly, do not eat in a hurry, also try not to talk during eating, start practising to take your dinner 2-2.5 hrs prior to your bedtime..

It's good that you've started taking Yogurt on daily basis(Yes probiotics are good too, you can continue them for a while), they are in fact rich in healthy bacteria for your gut functioning..

Try to avoid milk in direct form.. also avoid certain foods which predispose to excessive gas formation (i.e. Cabbage, cauliflower , turnips, radish etc.).. Avoid fizzy carbonated beverages.. take fresh fruits instead of packaged fruit juices..

Please follow all these instructions at first, and let me know how you stay in the due course..if despite following all these, symptoms do not improve/worsen further then I'd suggest you to schedule an appointment with a Gastroenterologist to for a thorough clinical evaluation and few relevant investigations (USG abdomen, Hemogram, ESR and stool routine microscopy) to look in to it further..

Let me know if there's any further queries, i'll be glad to guide further..

Take Care
Kind Regards
