What the gallbladder does, and why you can live without it
The gallbladder does not make bile: it stores it. The liver produces bile continuously and the gallbladder concentrates and keeps it, releasing it in one go when fatty food reaches the intestine. It is a reserve system, efficient but not indispensable.
When the gallbladder is removed, the liver goes on producing bile exactly as before, only now it flows continuously into the intestine instead of in bursts. Fat digestion still happens; what changes is the rhythm. That is the whole physiological difference, and it explains both what happens in the first weeks and what happens afterwards.
The first two weeks
Discharge is usually at 24 hours and, in selected cases, the same day. Pain is moderate and controlled with oral analgesics. Discomfort in the right shoulder is very common and surprises anyone not expecting it: it is caused by the gas used during surgery and disappears on its own in a day or two.
Diet is reintroduced in stages: the first days without fat, with soft foods and small portions, then widening as tolerated. Walk short distances several times a day from day one. And respect the lifting restriction even when you feel well: hernias at the instrument port sites appear from lifting too early.
From week two to month three: adaptation
This is the period least talked about and the one that generates most questions. The body is adapting to receiving bile continuously, and during that time looser or more frequent stools are common, especially after fatty meals. In most people that settles over weeks.
The strategy that works best is not a list of forbidden foods but eating smaller, more frequent portions and reintroducing fat gradually instead of returning all at once to fried food. What tends to cause most discomfort at first is fried food, cream, cured meats and very large meals.
In the long run
Most people end up eating everything. A minority is left with a tendency to looser stools or reduced tolerance of very greasy meals, generally managed with dietary adjustments. If that tendency is persistent and troublesome, specific treatments exist and are assessed in clinic.
What should not be assumed is that any later digestive symptom is «because they took my gallbladder out». If the pain that led to surgery returns exactly as before, or if yellowing, fever or severe pain appears, it needs assessing: there may be another cause, including a stone left in the bile duct. That is investigated, not attributed.
The signs that mean calling without waiting
After a cholecystectomy, a set of findings does not admit waiting: FEVER ABOVE 38 °C, abdominal pain that increases instead of settling, YELLOWING OF SKIN OR EYES, very dark urine, persistent vomiting that prevents keeping fluids down, or redness and discharge from one of the wounds.
None of those necessarily means a serious complication, but all deserve a call the same day. They are handed over in writing at discharge, together with the contact number, precisely so that nobody has to search for them online at three in the morning.

One consultation with your ultrasound or CT in hand is worth more than ten internet searches. Book by phone or through the form and you will be told what is there, what it means and what your options are.
