People often think that constipation primarily affects the stomach. But recent research shows that several common constipation drugs may also help preserve your kidneys by making your gut healthier and lowering inflammation.
This isn’t a “kidney treatment,” but knowing how these two things are connected can help patients make better choices regarding their kidney and gut health.
Why Constipation Is Bad for Your Kidneys
Constipation is more than just being uncomfortable; it can also mess with the gut–kidney axis, which is the two-way link between kidney function and digestive health.
When you can’t go to the bathroom:
- Substances that are bad for you stay in the intestines longer,
- The amount of inflammation goes up, and
- These poisons can get into the blood.
- Causing your kidneys to have to work harder to get rid of them.
This extra work may be hard for persons with chronic kidney disease (CKD) to handle.
How Some Constipation Medications Can Help the Kidneys
Recent medical talks and new investigations have shown that osmotic laxatives and fiber-based laxatives may help the kidneys work better in an indirect way.
- They stop toxins from building up in the intestines.
Some laxatives assist the body get rid of waste more often, which lowers the amount of “uremic toxins” that build up and can stress the kidneys.
- They help keep gut bacteria in equilibrium.
Laxatives that are excellent for the gut, like lactulose or fiber supplements, help good bacteria grow.
A gut that is healthy means that fewer toxins that cause inflammation go to the kidneys.
- They help decrease inflammation
Kidney disease is connected to long-term inflammation.
Inflammation in the digestive system can go down if bowel movements get better.
- They might help your metabolism work better
Getting rid of constipation typically helps with:
- levels of sugar in the blood
- High blood pressure
- Digestion
High blood pressure and high blood sugar are both substantial risk factors for renal disease.
- They ease the stress on kidneys that are already weak.
In the early stages of CKD, lowering the amount of toxins in the body may help the kidneys do their job a little better. This is not a cure, but it is good for overall health.
Important: This is NOT a way to treat your kidneys.
Medicines for constipation do not fix renal disease or repair damage.
They only help the gastrointestinal system, which might indirectly ease the stress on the kidneys.
Before taking any laxative, you should always talk to a doctor, especially if you have:
- CKD
- Diabetes
- High blood pressure
- Illness of the heart
- A history of transplants
Taking medicine on your own can be bad.
People with kidney problems have safer choices.
These are usually seen to be gentle if your doctor says it’s okay:
- Lactulose is a common osmotic laxative.
- Isabgol (psyllium husk) fiber
- Stool softeners in small amounts
Don’t take stimulant laxatives unless your doctor tells you to. They can make you dehydrated.
When Should You Go to a Kidney Doctor?
If you are constipated and have any of the following:
- Edema in the face or feet
- High blood pressure
- Feeling exhausted or weak
- Pee that is frothy
- Less urine production
- Diabetes that makes it hard to digest food
These could be early symptoms that your kidneys are under stress.
