Short Gut and Vitamin D
I had the middle section of my small (17 ft) intestine removed and am in reasonably good health, but don't seem to be able to absorb Vit D. I take 5,000 units a day of an OTC product along with Ca, Glucosamine, Prilosec, and other daily pills.
My diet to varied and my weight stays reasonably level in the high 170's - I'm a male, 64 yr old.
I do take a shower a day and am fair skinned. My skin has not been the same since my surgeries 5 years ago, but is not extremely dry.
I live in the mid-altantic region and play tennis year 1-2 times a week, so I do get some sun.
