Constant bloated feeling is also called
dyspepsia. It can have a variety of causes ranging from your diet to even cancer. of course, the latter is much less common. do you have any other conditions or symptoms? It makes a big difference. For example, constant
diabetes for many years will cause autonomic
nerve problems that leads to decrease G.I. motility and constant bloating/fullness. One other very common cause of constant bloating/dyspepsia is
H pylori infection in the stomach, which could be easily eradicated by two weeks of antibiotics.
I know this problem can be very stressful/annoying, but there are at least symptomatic treatment which should prove helpful. What treatments have you tried so far? What other conditions do you have? these are only sensual to determine what is the next best step.
if you have tried many options of treatment and none of them works, or if your symptoms are worsening, I suggest you visit your doctor and get some imaging/scopes to rule out any severe conditions. If no other causes is found, chronic symptomatic treatment will have to be the way, such as anti-acids.
