If you have ulcerative colitis, you’re already playing defense. You manage symptoms, dodge flares, try to live normally. Good job. Keep doing it.
There is a side effect, though.
The meds that save you might be eating your bones. Specifically, glucocorticoids. Steroids like prednisone. They quiet the fire in your gut, but they weaken the skeleton.
Why? It’s a messy combination. Inflammation itself eats at density. Malnutrition helps. Inactivity helps. Low testosterone in men, definitely helps. The result? Osteopenia. Or worse. Osteoporosis.
It’s silent.
Most people don’t know their bones are hollowing out until one breaks. Wrist. Hip. Spine. The kind of fracture that ruins a weekend. Or a life.
Between 18 and 42 percent of IBD patients hit this mark. Men over 50 need to worry. Women need to worry. Everyone with UC should probably worry.
So, you do nothing?
No. Here is how you keep your calcium in the jar, not in the hospital.
1. Scan The Damage
You can’t fix what you can’t see. Get a DEXA scan. It checks density. Madalina Butnariu from Ohio State says if you are on steroids or have active inflammation, this isn’t optional. It’s routine.
If the numbers look bad? Don’t panic. Refer to a specialist. Fix it before you break something.
“We refer them to an appropriate specialist… once the scan is consistent with osteoporosisis.”
2. Eat The White Stuff
Calcium builds bone. Simple physics. If you are deficient, or have been on steroids, you need 1,200–1,500 mg daily.
But do not gulp it all at once. The body chokes. Absorbs max 600 mg. Split the dose. Morning. Night.
Where to find it? Dairy. Cheese. Yogurt.
Hate milk? Almond milk works. Tofu. Collards. Kale. Fish with soft bones. Fortified juice. Drink your bones in, if you have to.
Flares make absorption harder. Double down on calcium during bad days.
3. Sun Or Synthetics
Vitamin D moves calcium into the system. Without D, the calcium just sits there.
About half of UC patients lack it. The sun helps, sure. But if you stay indoors, take the pill.
Jami Kinnucan at Mayo Clinic targets blood levels above 30 ng/mL. He gets there via supplements and food. Egg yolks. Fatty fish. Fortified milk.
Just check your blood. Adjust accordingly.
4. Drop The Steroids
This is the big one. Steroids are bone-killers.
Joseph Feuerstein at Beth Israel Deaconess is blunt. Four to six weeks of high doses raises osteoporosis risk. Significant risk.
He wants steroid-sparing agents. Biologics. Immunomodulators. Use the heavy artillery only when the building is on fire. Not for maintenance. Ask your doc. Can you switch? Maybe you should.
5. Watch The Booze
Alcohol doesn’t pair well with bones. Two drinks a day tops it out for healthy adults. For you? Probably less.
Alcohol triggers UC flares. It stresses the system. It eats the bone.
One drink a day. Or none. Discuss with a dietitian if you want to keep the beer flowing. But don’t be naive about the cost.
6. Burn The Cigs
Smoking is bad for lungs. Bad for guts. Terrible for hips.
Quit. Really. It drops the fracture risk. It drops the cancer risk. It’s one of the easiest fixes in this entire list. Do it.
7. Move Your Weight
Bones need stress. Good stress. Weight-bearing exercise triggers growth.
Run. Jump. Dance. Tennis.
Broke a bone? Or afraid? Dial it back.
Walk fast. Use an elliptical. Swim. Keep the heart beating and the legs moving without slamming the joints. Motion preserves what structure you have left.
There is no perfect cure for UC. No perfect life.
But you can choose density. You can choose strength. It starts with a scan. A supplement. A conversation about switching meds.
Don’t wait for the crack to sound.
