Ardhastama Sani, Janma Guru and Janma Rahu at the same time, is one of the worst combination for a person to go through. So there are no words to express the physical ailments you had gone through. Mental stress and tension would have peaked so many times for you. Now the good news is, benefic Jupiter is on your 2nd house.
It will help you a lot to recover from ailing health. If you have gone through any surgeries, you will start seeing great recovery. If you are due to do any surgeries, then wait at least until end of Sep 2016. You will maintain good diet and exercise going forward. You will start reducing your excess weight and will obtain sound health during this Jupiter transit. Keep enough prayers to gain positive energies faster.
When Saturn moves onto your 5th house by early next year, can cause more mental stress. But with the strength of Jupiter, you would be able to manage the stress level.
