Thanks for your question on Health Care Magic.
I can understand your concern.
Prostate cancer is
hormonal cancer. So hormonal imbalance is ones of the cause for prostate cancer. At the same time hormonal imbalance can also cause obesity.
So better to first get done hormone levels and if imbalance is there than correction is needed for
weight loss.
Also consult dietician and get done proper diet chart for weight loss.
Drink plenty of fluids orally. Start high fiber diet. Avoid
stress and tension. Avoid oily and spicy food. Avoid junk food.
Do regular
aerobic exercise like swimming, cycling and jogging.
Avoid commercially available drugs for weight loss as none of them are US FDA approved and having many side effects.
Once you loose weight your sleep will also be normalized and need of CPAP will also reduce.
Hope I have solved your query.
Wish you good health. Thanks.
