Do I have diabetes. Deal all of them?

Hello. Sir I understand your problem, I think you should know that a person suffering from diabetes have problem with insulin production or insulin receptors on the cells leading to imbalance in glucose levels in the body. This leads to easy tiredness, muscle aches, breathlessness on doing strenuous work, irritability, it can affect various organs of the body like kidney leading to frequent urinating, glucose in urine or affect eye leading to diminishing of vision or GIT leading to loss of weight etc. So based on the history you have given you have typical symptoms of diabetes and as far as the forgetfullness is concerned it might be due to stress of having this condition along with the glucose imbalance seen in diabetes which can also cause disorientation and confused state sometimes if the sugar level is not controlled. So I kindly advise you to monitor your blood glucosr level and follow a regular drug schedule. Coming to the breathlessness- as you only mentioned that, you are a smoker. Smoking reduces the general capacity of lungs on chronic use, which coupled with your diabetes can aggravate breathlessness. So my advise is to stop smoking. Consult a diabetologist for further management of your condition.
