Waking Up to Pee at Night? The Problem Starts During the Day
In a Nutshell
Nighttime urination stems from daytime fluid retention in the legs caused by high insulin and glucose, which damage the endothelial glycocalyx and allow protein and fluid to leak into tissues. When lying down, gravity shifts this retained fluid back into circulation, filling the bladder and triggering nighttime urination. The solution is to eliminate evening carbs and snacks, lower insulin through a low-carb diet, and move fluid out before bed via walking or leg elevation rather than restricting fluids or salt.

If you are waking up to pee at night, your problem is usually not in your bladder or your prostate. It's actually in your legs. A challenge test involves placing a large cup in the bathroom next to the toilet. When waking up in the middle of the night, collect the urine in a cup and measure how much urine comes out. Most people are not just passing a few drops of urine. They're passing at least one or two cups of urine. That is a normal full bladder of urine, which means the bladder is not failing. The bladder fills up to its capacity and tells you when it's full, but the real question is why a full bladder of urine is being produced in the middle of the night. The answer has nothing to do with your bladder or your prostate. It has everything to do with something lower than that, which is your legs. The origin of the urine that came out at 2:00 in the morning is not the liquid that you drank right before bed. It was the liquid that you drank in the earlier part of the day, probably around 4:00.
By the time that we reach 80 years old, nearly nine out of 10 people are waking up to urinate at night. There's a big risk getting up in the middle of night in the dark, tripping, falling, fracturing. The second test that can be done right now is an edema test. This is a test to see if you're holding fluid. Right by the front part of your shin, press firmly into your lower leg. Hold it for about 5 seconds. If it leaves a dent, there's fluid sitting inside your tissue right now. An average person who's normal, who doesn't have edema, is holding 6 lb of fluid in the legs. This refers to below the knee, the lower legs. Both of them hold normally about 6 lb of fluid. Fluid retention does not occur because the person is drinking too much fluid. Fluid retention also isn't necessarily caused by consuming excess salt if everything is healthy.
The question is what is holding all this fluid in your legs. High glucose and higher amounts of insulin. Insulin has a purpose of storing fat, but it has another huge purpose. Insulin is the most powerful sodium retaining hormone in the entire body. Doctors don't do a fasting insulin test. If you get your fasting insulin test, you want it below five. Higher glucose, higher insulin causes the kidneys to hoard salt. Glucose can be looked at like another type of salt because glucose retains water. A diabetic usually has massive retention in the lower legs. They usually are peeing a lot and they're thirsty a lot. They are getting rid of fluid, but they're retaining a tremendous amount of fluid. There's actually a diagnosis for that called insulin edema. You'll see it around the eyes, too. You get puffiness around the eyes. You might see fluid around the face, the arms, definitely the lower legs.
What's really happening in the capillaries and the blood vessels in the lower legs is you normally have this very thin layer. It's called the endothelial glycocalyx. Think about it like a very thin microscopic layer of this sugar gel coating. Its job is to act as a tight barrier to keep the fluid sealed inside that blood vessel. When you just have hours of high blood glucose, that protective layer gets shredded and stripped away. Without any barrier, protein starts leaking through the little tiny crevices and the holes into the tissues. Wherever the protein goes, you get actually fluid retention.
On the flip side, notice when someone goes on a low-carb ketogenic diet. What's the first thing that happens? They drop a tremendous amount of fluid. Sometimes 5 to 11 lb in the first few days. The kidneys were finally able to dump the trapped salt and the fluid that's been sitting in your legs. This is also why, if you consume a very heavy carbohydrate meal and maybe snack in the evening, you are directly stripping out this lining and you'll probably end up in the morning with fluid retention. But not only that, you probably are getting up through the night to pee.
The question is why people are having more urination problems at night, maybe even more than during the day. That's because of gravity. You're lying on your back. Gravity is no longer pushing the fluid down into your legs. Slowly, the fluid from your legs is coming back to the heart. And it's being filtered by the kidneys and it's ending up in your bladder as a full bladder of urine. Once a night, twice a night, three times a night, it could be four times. People have been talked to who were getting up 10 times a night to urinate.
Even when someone has sleep apnea, the restriction of breathing causes more pressure on the heart, which causes more activation on your kidneys to release more urine. Another huge cause of getting up through the night is side effects from a lot of different medications, high blood pressure medications, diabetic medications. A lot of those increase the production of urine and that's a completely different situation. But you need to know about it so you can deal with that with your doctor. Typically, stopping drinking after 6:00 p.m. is not the ultimate solution to fix your problem. Restricting your salt is not the ultimate solution. What is the solution is fixing the sugar. Then you'll fix the salt. Then the fluid dumps. Ideally, a person who's healthy should be able to drink in the evening, even have some salt, and not get up through the night. The speaker doesn't get up through the middle of night. They don't have fluid retention like they used to. And they drink a tremendous amount of water in the evening. This is actually not a hard problem to fix.
The first thing you need to know is the snacks at night are the worst thing you could possibly do because you're going to keep your insulin high right before you go to bed. The worst time to snack at all is right before bed. It's really bad. You should have a sign that says the kitchen is closed after you have dinner. And then no food after that. Number two, if you're able to walk after dinner for 10 minutes, it'll help burn off the glucose, and all that fluid accumulation in the lower legs can be pumped out, but you also burn off the sugar.
A lot of people ask what supplements are recommended. If you go to Amazon and type Dr. Berg supplements, you'll find more information. The other thing you can do is elevate your legs in the evening. Let's say you're watching TV, lie down on the couch, bring your legs up. The fluid will start coming down. You'll be able to pee out that fluid before you go to bed. As you fix your diet, fix the sugar, go on a low-carb diet, and if you're not familiar with the ketogenic diet, there's a link down below of the simple version of exactly how to get started with intermittent fasting. There's a free download that's the daily routine in a checklist. This is a routine that is used every day to feel like you're 18 years old even though you're 60 years old and it's given for free. There's a little link down below, click it and definitely download that.
Sleep apnea was briefly mentioned. Some people have that. If you do have that, you need to watch the video to learn about it and how to correct it right here.
