I hate to be "picky" about the use of the word "bloating" but like many other words patients tell their doctors as their symptom, those words have to be explained by the patient to be of value to make a diagnosis. The symptoms such a "dizziness" can represent different sensations or impairments such as true vertigo, feeling of about to faint, instability standing or walking due to impaired sensation from the legs or anxiety conditions as examples. "Constipation" is a relative symptom and the doctor must try to detail the symptom from the patient to know whether it means hard stool or frequency of bowel movements and whether the frequency is unusual or abnormal.

May I be a bit more "picky"? The adjective "constant" needs to be explained since "constant" could mean continuous (never going away) or a repeatedly intermittent symptom that doesn't stop.
If, it is intermittent but ongoing then it is important to know what gives temporary relief. Is it a bowel movement or passing gas?

What I am getting at is that all the suggestions given in the previous responses are of importance as causes of digestive distress but "bloating" could also be used as a patient's expression of a distended abdomen due to fluid in the abdomen and there could be many other different causes for that to occur.

Why am I "picky"? I suppose it is that I am a doctor and a teacher of medical students about how to get a history to help make a diagnosis. ..Maurice.

Your symptoms as described now sound like irritable bowel syndrome (IBS) or lactose intolerance (if you drink milk) but you should continue to consult with your physician regarding followup and management. ..Maurice.
