How much can I take off by sweating

[hexoffender]

Ok this might sound grosss, but I dont care. I am pretty active for having been on D for >5 years. I go to the gym 4-5 times a week, swim regularly, and Hike about 5-8 miles every weekend. With all that, I sweat alot... I didnt always though. When I had my transplant I hardly ever sweat. Of course I was also peeing then too. But especially in cold weather, when hiking, I can sweat so much my shirt will be completely soaked. Im guessing I sweat at out at least .5 kg. This morning I went swimming, and had to wait after my swim for my sons lessons to finnish. So by the time I went to the sauna, I was already mostly dry. Before I had alwys gone in the sauna wet. But after 5 minutes, I looked lik I had just ot out of the pool, and sweat was gushing out of me. So now Im thinking I might be able to pull at least 1 kg in between treatments, just by going to the sauna. Oh fyi, Im terrible about sticking to my fluid restriction. I dont even know what it is, so I try to just drink as little as I can, but I eat a ton of fruit, so thats probably what kills my fluid. I usually have to pull off 4 kg/treatment.

Have you tried weighing yourself both before and after you exercise, hike, swim, etc? It might at least give you an estimate of how much you're losing in fluid.

I have never been able to sweat. Even when I was playing hard field hockey, and lacross, I never ever sweated. Maybe that should have been an indication of my kidney disorder? I don't know. But I do know I worked out hard and ran at least 5 miles every day and still never sweated. I'd be blessed to sweat and now to pee more than 1 cup a day!

I used to lose a lot more water than 1 kilo, when I stayed in a sauna for 45 minutes.

BTW, perspiration contains sodium and potassium too--about 900 mg sodium and 200 mg potassium per kilo of sweat.  So you can excrete excess sodium by sweating too.

That's why athletes often choose to rehydrate with sports drinks (Gatorade) rather than pure water.  Losing all that sodium and potassium means that if they drink pure water to rehydrate, they will have too little sodium and potassium for their fluid volume--and that can be dangerous.

If you're taking off 4KG there is probably excess sodium in your diet. Fruit has moisture, all food has some moisture, but that would be a lot of fruit. So then the sauna is a twofer - water and salt.

The thing to remember is you can get dehydrated by dialysis, so you need to be extra aware of how you're feeling. If you start to feel at all light headed when sweating take a break.

I will try to remember to weigh before I go in the sauna, but I hate using the scale at the gym. Its one of those ones with moveable weights. Im really careful about sodium, so I dont think its my diet. When I say alot of fruit... I mean alot  of fruit... especially apples I eat 10-12 apples a day, grapes(half a bag), and whatever is in season. I probably also drink too much water. I have a Kleen Kanteen that holds 16 oz, I sip on that all day at work.

@RightSide... I dont know if i could last 45 min. in the Sauna, I did 20 the other day and thought I was gonna die.

depending on how much you weigh and how tall you are......i don't understand why you are concerned about 4kg. we have a guy at my center that gains 8/9 kg from monday to wednesday. now he's someone that isn't taking care of himself. i occasionally gain 4 over a weekend and even my doctor isn't worried.  you sound like you're doing well.

[Bill Peckham]

It does depend on your body size, the most recent data I've seen says you need your ultra filtration rate to be below 10ml/hour per kilo of weight. So you'd need to weigh more than 100KG if we're talking about removing 4liters over a four hour run.

The vascular system is like a balloon the more you inflate and deflate, gain and loose fluid, the more it looses its elasticity.

That's a lot of fruit hexoffender. How are your potassium and albumin levels? That said, better to eat fruit than drink juice.

The vascular system is like a balloon the more you inflate and deflate, gain and loose fluid, the more it looses its elasticity.

Are you sure about that? Because I'm supposed to get a 2nd angioplasty on my fistula, even though it's now flowing fine, but I'm having 2nd thoughts if inflation/deflation is going to cause damage to it in the form of less elasticity. Also I'm not too happy about going under the fluoroscope again. Lots of ionizing radiation there.

[Bill Peckham]

Fluid gains and angio are different processes. With fluid gains it is as if your whole vascular system is being inflated; with angio there is literally a balloon that is inserted into the fistula to reverse a stenosis. The issue with fluid gains isn't the one time it happens but when it is happening treatment after treatment, inflating and deflating the vascular system 100 times a year, year after year. It's that cumulative effect that causes dialyzors problems.

There are risks with angio, as with all procedures, but they are different risks than those caused by high fluid gains. And no one gets a 100 angios a year.

Thank you Bill!
