Are the pills you taking killing you or helping you, can improving your diet reduce your dependence on medication? There is more than one answer to this question. First I do not advocate you changing your medication, unless you have had a careful consultation with your doctor. 

    There are many medications which do have an effect on your appetite. They may cause a stomach upset. They may cause you to be nauseous, and not want to eat. They may cause you to retain water, and they may also cause you to be hungrier than normal, among may other side effects.

  First learn all there is to know about your medications, then with your doctors approval, you can look at the options for changing the way you eat to improve the way that the medications work in your body.

    If you are overweight, in many cases, getting that weight under control has a chance of reducing your dependence on some types of medication. If you have been generally unhealthy and you are able to improve your health and diet significantly this will do two things. It will give you a better fighting chance at maintaining your health and quality of life, even if you have to maintain your current medication level. If your disease is obesity related in many cases you might find your doctor telling you that you do not need medication or are able to substantially reduce your levels of medication if your weight is significantly under control.
