This topic is about understanding how having an ileostomy might affect the absorption of vitamins and nutrients, particularly in relation to hair loss. The person sharing their experience has had an ileostomy for 12 years and is noticing significant hair thinning, despite taking high-quality vitamins and omegas. They suspect that the lack of a colon might be affecting their nutrient absorption and are wondering if taking more vitamins could help.

Here are some helpful suggestions and insights:

1. Check key blood levels first:
- It's important to ask your doctor for a comprehensive blood test to check your levels of vitamins, minerals, and thyroid hormones before increasing your vitamin intake.
- Pay special attention to vitamin B12, as many people with an ileostomy need regular B12 injections.

2. Investigate thyroid function:
- Hair loss can be a sign of hypothyroidism. Some people have found that their thyroid levels dropped after an ileostomy because their bodies didn't absorb the medication well, leading to severe symptoms.
- Get your thyroid-stimulating hormone (TSH) and T4/T3 levels checked as soon as possible, as untreated low thyroid can be dangerous.
- If you're taking levothyroxine or a similar medication, you might consider:
- Chewing the tablets to help with absorption.
- Asking for a different form of the medication, like a liquid or gel cap, if your levels are still unstable.

3. Optimize supplement form for better uptake:
- Large, hard pills and time-release capsules might not be absorbed well and could pass through your system intact. Breaking them in half or opening capsules (if safe) might help, but always check with a doctor or pharmacist first.
- Consider alternative forms of supplements:
- Quality liquid multivitamins.
- Chewable tablets.
- Biotin supplements, as some people have noticed improvements in hair and nail strength.

4. General absorption notes:
- Most nutrient absorption happens in the small intestine, so having an ileostomy doesn't automatically mean you'll have deficiencies. However, if food moves through your system quickly or if you've had part of your small bowel removed, it might reduce the time your body has to absorb nutrients.
- Pay attention to how you feel overall—your energy levels, hair, nails, and skin can be good indicators. Make any adjustments under the guidance of a healthcare professional.
