Bloating and early satiety aren t uncommon in long term diabetics. The more common cause is functional dyspepsia (which is usually relieved by antacid combinations, or prescription drugs like H2-blockers eg. Famotidine, Ranitidine; or PPIs viz. Pantoprazole-taken as 40mg once daily before breakfast for 4 weeks, Omeprazole, Rabeprazole-taken as 20mg once daily before breakfast for 4 weeks). GERD, Gastritis etc may present with similar features. Avoid lying down immediately after meals, increase frequency of your meals making each meal lighter, chew well, and follow your diet plan. However, Diabetic Gastroparesis is also possibility which is usually treated by a combination of Clidinium bromide and Chlordiazepoxide. Since all the drugs mentioned are prescription drugs in most countries, it would be prudent to attend the clinic of your consultant. As for your spondylitis, you need to mention the areas involved, as the exercises vary accordingly. Take analgesics (painkillers) like Paracetamol 15mg/kg body weight (you have not mentioned your body weight). Remember, if you actually have gastritis, some analgesics could worsen it, so follow the advice of your consultant before consuming them.
