Health Condition Limitations

I am pretty strict on staying on my diet. It consists of 1700cal. 1500 sodium 100 or less Sugar. I have a compensated liver which was caused by Hep C. For 5yrs I’ve stayed on my diet. 2 or 3 times I got depressed of losing the battle. I’m 6’ 4” male age 61 now. But I went in organ failure in 2006 and stopped it after 3x of Interferon 54 months. I have 1/8 of liver left. I normally went under 270lb and in shape of 240lb. But when I went in liver failure I blew up like a balloon. Fluid is a problem. If I keep the sodium under 2000 my RXs removes the excess Daily. I’ve dropped down as far 295lb was my lowest. But then as usual no good reason I can gain as high as 10lbs in 2 days. This was on a long 1000 mile drive and it’s hard to stay perfect driving. It comes on fast but it drops off slow! That 10lbs will take 2 weeks. I’m able to be a little bit active. But I was bed bound and I’ve fought back enough that I walked around Disney world! I was not able to walk at all for 3days. A hard liver is not all. The RX I took caused my lungs to be diagnosed as emphysema, plus I have the swelling accompanied by Rheumatoid Arthritis. Just recently I’m Type 2 diabetic but well controlled! What is the answer. Or is there one? I’ve come back a good way but if I’m lighter I’m able to do more and exercise more. Anyone in the know? Maybe similar csituation. What’s bad a doctor gave me the Hep C virus before it was able to be diagnosed! I still worked 70-80hr work weeks. I was athletic prior but collapsed 17yrs after with liver failure in 2006. I’m starting my own internet based business now! At 61yrs old I’m going to have the most success I’ve had in my career. But only with Gods Strength and my faith in His provision. And His people that maybe know the answers!!
