I always get up at night to pee

Large volumes: several possible causes.
If you urinate a lot at night (more than a third of your total in 24 hours), there could be several explanations. “If your water intake is significant during the day, reaching 2 liters or more in total, you may simply be drinking too much,” warns Professor Desgrandchamps.

The right thing to do: In this case, and only in this case (there’s no need to be thirsty during a heatwave!), reduce the amount of water you drink.

“A second possible cause is sleep apnea,” he explains. “This condition causes the kidneys to secrete a hormone during the night that forces them to work harder, thus eliminating the water consumed during the day.”

The right thing to do: consult your doctor, who will take appropriate measures.

The final possible cause: a form of heart failure. The heart has difficulty pumping blood from the legs, and during the day we feel heavy in our legs… “In this case, at night, once we lie down, the blood rises more easily and the kidneys do their filtering work, which they were unable to do during the day, and, consequently, we get up to urinate!” explains Professor Desgrandchamps.

The right thing to do: A simple solution is to take 20 to 40 minutes at the end of the day to lie down with your feet up, or even against the wall. And urinate before going to bed!

Finally, if your doctor has prescribed diuretics, remember to take them in the morning, and certainly never after 6:00 pm…
