You are still under Jupiter Mahadasha till 18/8/2019. Jupiter being lagna lord, karaka of good health, placed in 3rd house aspecting 11th house and transiting in 11th house from Sep 2017 offers a great chance to push for remedy to get into better shape.
Try to get things sorted before Saturn Mahadasha as much as you can. As Mr. TMR mentioned, following medical advice and treatment will help.
Also chanting Jupiter beej mantra 21000 times in 21 days will help find the right way.
