Drinking a litre of water overnight is this normal?

[Blueskyemily]

I've always been someone who needed to take a glass of water to bed but just recently it's getting worse.

I can easily drink a litre overnight and when I first wake up the next morning. My husband rarely finishes a small glass.

Is this normal or anything to worry about? I'm 35 and no other issues except sometimes tiredness but I'm fairly certain that's linked to having two kids?

Do you drink enough during the day?

I'd certainly get checked! How much do you drink in the daytime? Could be diabetes or thyroid problems.

Could it be diabetes?

I would be up peeing all night. I do think it sounds quite unusual

I wouldn't say that's normal, no. DH and I never take water to bed so we're at the other extreme but I would have thought one small glass was more usual.

In summer I’ll often have half a water bottle before bed (250ml ~) and another half a litre within 15-20 mins of waking up. Occasionally another sip during the night.

I have 2l+ during the day (not counting that 0.5-1l) so I’ve never been too concerned about it.

Is this just happening now the weather is getting warmer, or has it been progressing for a while? Any changes in diet - eg saltier meals, less fruit and veg…?

I sometimes would on warm nights as our house tends to be very warm upstairs. However on a normal night it would be at most 1/2 litre and that is when I had eaten something salty.

It's normal for me. 34, no diabetes or prediabetes or anything, which could cause excessive thirst. I've taken 2 pint glasses to bed with me for years. And I put a fair amount away during the day too.
I just assume I was a trout in a previous life.

If you’re drinking a lot during the day it could be an issue, but if you’re not then you’re just going to bed dehydrated and drinking it then.

This.

I drank almost this much a night when I was pregnant. Maybe get your thyroid and diabetes checked just to be sure.

It’s not always an issue, I grew up drinking 2.5-3l of water a day (warmer climate, regular physical activities and very health-conscious parents), and my body is just used to drinking those amounts.

That said, the OP should get checked if they think something is wrong.

Sounds like diabetes.

I always take a glass of water to bed, have done since being a kid. I'll have a few sips overnight.

It varies a lot for me but if ive had a busy day and not had time to drink much, if ive exercised in the evening, especially in this weather, my 3/4 litre (wine bottle) is sometimes not quite enough. I think you should consciously try to drink more in the daytime and see if you still get so thirsty at night. If it continues, a blood sugar check (possibly you can get one done at a pharmacy) might be a sensible next step.

If you'd always drunk a lot of water at night, I would think its just your metabolism. If your need to drink is increasing, then I would think its something to be wary about. Are you drinking more during the day as well? Are you urinating more in the night? Never harms to get a blood test just to be sure everything is Aok.

Go and get a diabetes check!

I drink at least a litre in the night often more. I've recently had all my bloods done and there's nothing untoward. I think I sleep with my mouth open which gives me a very dry mouth - hence waking and needing to drink. I also spend the night peeing as well - no surprise! Basically my nights are very busy ha ha!

I always drink a lot overnight if I haven't drunk much during the day.

Not normal unless you're somewhere hotter or haven't drunk enough in the day. DH could easily get through a litre overnight - he was then diagnosed with T2 diabetes

Thanks everyone. Ok so I think I'm going to make a real effort to drink plenty during the day for the next few days and see what happens. If no improvement I'll call the GP!

Have you had COVID by any chance?! I was drinking 1-2 L per night for about 3 months after! Was sent for diabetes test, but no. It settled down after about the 3 month mark.

I can do that after I’ve eaten a dominos or takeaway curry…

Wow I can’t drink at all for at least 2hrs before bed or I need to pee. So this is highly unusual to me but seems such a range here.

Do you have a lot of caffeine during the day? Some people are more susceptible to the diuretic effect of caffeine, so at night when they stop having so much caffeine are dehydrated. I'm like this and have to drink about a litre of water through the night if I have lots of caffeine. I also have to drink a lot during the day if I have lots of caffeine. Other people I know can drink nothing but tea or coffee and don't get this thirst at all. I definitely do not have diabetes, btw
