4:47 Vitamin B1 to improve urine stream
7:28 Slow urine flow after menopause
Men are told that a weak urine flow is a prostate problem, and women are told that it’s caused by aging or childbirth, but what’s the truth?
If you wake up with a weak urine flow that improves after you drink coffee, this is not a prostate problem. This is related to a problem with your autonomic nervous system and bladder.
A weak urine stream can also be caused by a weak detrusor muscle. This can happen if you’re fatigued, sit frequently, or have insulin resistance. If you’re constantly stressed, your bladder problems might be related to issues with your parasympathetic nervous system.
If your weak urine flow only occurs at night or in the early morning, this is related to your body’s circadian rhythm.
Bethanechol is often used to treat urine flow problems. This medication primarily affects the autonomic nervous system. Vitamin B1 can naturally affect the nervous system to help with a weak urine flow.
Vitamin B1 has many benefits, but you should also focus on correcting the reason you’re deficient in the first place. Following a low-carb diet, reducing your alcohol intake, and intermittent fasting can help correct insulin resistance and improve urine flow problems. Vitamin B1 can also help reduce stress levels.
A weak urine stream after menopause could be related to estrogen. Estrogen greatly influences nitric oxide, which can affect vasodilation and blood flow. Sun exposure and exercise can help. Addressing your indoor lighting and sunlight exposure frequency can also help address urine flow problems associated with your circadian rhythm.

| 0:00.0 | If you have a weak urinary stream, anytime during the day or night, you're in the right place. |
| 0:05.3 | I'm going to talk about exactly what's behind this and give you practical things that are fairly easy to do to correct it. |
| 0:12.9 | Most people are told that this weak urinary stream is a prostate problem. |
| 0:17.5 | If you're female, you've been told it's your aging or from childbirth and you're just |
| 0:22.8 | going to have to live with it. Not true. A weak urinary stream is usually not the prostate. It's usually |
| 0:30.1 | related to several other things. And the body gives us clues on what is causing it. But I want to |
| 0:37.3 | emphasize most of the time, it's not some type of plumbing problem where there's |
| 0:42.1 | some obstruction. |
| 0:44.0 | There's something else going on. |
| 0:45.5 | Here's the first clue. |
| 0:46.5 | You get up in the morning and you urinate and it's weak, but then you drink coffee and |
| 0:52.0 | it gets stronger. What does that tell you? |
| 0:55.2 | It tells this right off the bat. |
| 0:56.9 | It's not a prostate problem. |
| 0:58.8 | It's more of a problem in the nervous system, |
| 1:00.7 | specifically in your bladder, |
| 1:02.5 | because the bladder is a smooth muscle that contracts, |
| 1:06.3 | and coffee tends to help relax that whole apparatus. |
| 1:13.3 | So if the coffee improves your urination, |
| 1:19.6 | we know the problem is in your autonomic nervous system. I'm going to touch on exactly what that means in a little bit and what to do about it. The next problem with a weak urinary stream |
| 1:25.0 | has to do with a little muscle called the detruser muscle, which is not |
| 1:29.3 | really under your voluntary control. It's something just happens. You don't have to think about it. |
