This is why you have to pee so often in the morning

One glass of orange juice and you're practically glued to the toilet? Here's why.

At night, your kidneys filtrate less urine, and your bladder relaxes and holds more of it. Plus, a hormone called vasopressin instructs cells to retain water.

So considering those factors, it’s not surprising that your bladder may be quite full in the morning.

Then, is your first liquid a mug of coffee? Caffeinated beverages can have a diuretic effect.

Also consider whether you just have to pee a lot all the time. If so, see your doctor to check for a urinary tract infection (peeing would be painful) or overactive bladder.

Less commonly, needing to pee a lot could be a sign of a medical condition like diabetes (often accompanied by thirst) or uterine fibroids, which are benign growths (you might feel pressure or have heavy periods).

Again, in those cases, see your doctor.
