“Can obesity cause other health issues?”

It sure can. From a physical standpoint it increases stress in all of the joints which increases the need for joint replacement in the future and increases inflammation in the body; physiologically it increases the risk of diabetes, heart disease, cancers; psychologically it lowers self-esteem and increases depression. You mentioned that you are obese. I would recommend that you see a doctor who specializes in helping people lose weight.
