Hello,
I am not a doctor, so I recommend you consult with your doctor first because of your health condition.
I am going to recommend you to see this sites, these are two programs that might help you find solutions for your weight loss and also with your health, the natural way.
I have been researching because my mom has Parkinson, and I found this site of natural cures which is a discovery that is scientifically proven as a natural therapy that creates an environment within the body where diseases cannot thrive -- and enables the body to cure itself of disease; check it out here.
The other site I would recommend you to visit is the system that made me lose 16 pounds of junk in my intestines, now I feel healthier, energetic and even my skin and hair looks vibrant now!! and the best part is that I have not gain the weight back.
Once you have your system clean, it is easier to lose weight, it does make sense, doesn't it?
Here is the Site, but please remember to consult with your doctor first. Good Luck o you!!
