If ferritin level is high (double uln) but iron and tibc are low in pt. With remote gastric bypass, is iron replacement still recommended.?

If ferritin level is high (double uln) but iron and tibc are low in pt. With remote gastric bypass, is iron replacement still recommended.?

Probable: A high ferritin can be interpreted as an acute phase reactant or chronic inflammation, but if your iron level is low, this can suggest deficiency. Having gastric bypass does cause iron absorption issues including others such as calcium. Routine specific labs are recommended for all bypass patients. Have your primary take a further look at this whether you would need chronic iron supplements. ...Read more

How to absorb more iron after having roux-n-y gastric bypass surgery since iron is absorbed in the beginning of your small intestines, which is bypassed after roux-n-y gastric bypass, where else can it be absorbed enough to keep your iron level up

How to absorb more iron after having roux-n-y gastric bypass surgery since iron is absorbed in the beginning of your small intestines, which is bypassed after roux-n-y gastric bypass, where else can it be absorbed enough to keep your iron level up

Generally : Generally the malabsorption seen after a roux-en-y lasts for about 18 months and eventually diminishes, so iron absorption will likely improve at around that time. If you simply can't get adequate iron, make sure your doctor looks at your ferritin level and not just hemoglobin level. You may indeed benefit from iron infusion or if you happen to be a premenopausal women with a heavy period, you may benefit from discussing birth control pills to help diminish the degree of bleeding that occurs each month with your menstrual cycle. ...Read more

12 years post op rny, iron 20 & vitamin d at 10. Seeing a new dr that hasn't worked with deficient gastric bypass, is 325ferrous 3x and 2000d 1x okay?

Nutrition!: A gastric bypass is a very complex nutrition situation. If your physician has not dealt with it much i would suggest asking for a referral to a nutritionist or a bariatric center. That being said, the dosage of iron is fda approved treatment for iron deficiency, and the vitamin d is a reasonable amount. You have many nutrient levels that should be monitored and carefully watched! ...Read more

S/p gastric bypass sugery by you 12/2010. I have a high pth level w/low calcium levels , 4 tests all high, can this be parathroid cysts? Scan was ?

S/p gastric bypass sugery by you 12/2010. I have a high pth level w/low calcium levels , 4 tests all high, can this be parathroid cysts? Scan was ?

High PTH low ca: This condition is due to your gastric bypass. Calcium and vitamin D are absorbed in the small bowel. This is now bypassed. The PTH is elevated due to low calcium absorption and likely low vitamin D. This can be corrected medically, but in rare cases the bypass had to be reversed to correct the condition when it resulted in severe hypocalcemia. ...Read more

Had a report of CBD at 13mm w/pain in up adom & low bk. gastric bypass 18 yrs ago& GB removed. Is this common and what does it mean?

Normal CBD: After the removal of the GB the CBD increases in size to accommodate for bile storage after the GB is removed. The size of 1.3mm is normal post-chole. There can be other causes of the pain such as adhesions, gastric ulcer, or gastritis. It would be best to see a PCP or a surgeon. ...Read more

Can a hiatal hernia be caused by gastric bypass?

Can a hiatal hernia be caused by gastric bypass?

Typically not. : Typically, having gastric bypass surgery would not cause a hiatal hernia, however, obesity could. The hiatus is a natural opening in the body. Being overweight naturally stretches at this opening, causing the opening to enlarge and eventually becoming a hernia.Like taking a styrofoam cup and sticking a pencil thru it and start turning the pencil. The hole gets bigger and bigger. ...Read more

Since the gastric sleeve can cause complication with a sarcoidosis patient. Is the gastric bypass better to have done with sarcoidosis?

Since the gastric sleeve can cause complication with a sarcoidosis patient. Is the gastric bypass better to have done with sarcoidosis?

sleeve ; sarcoidosis: Neither one (bypass or sleeve) is better than the other with respect to sarcoidosis. Studies have shown that people on immunosuppressive therapy can safely undergo either operation. I would just decide which operation is best for you. In a healthy ; moderately obese person, either operation is fine. If you have gerd, diabetes, or have a bmi over 50, bypass is preferred. ...Read more

I have a high level of Vitamin B12 (2000). I wonder if taking METANX CAPSULE PANAM could be causing my problem? Also I did have a gastric bypass in

Probably: Metanx does, in fact, contain B12 vitamin supplement. It also contains the active form of folic acid, known as methyl folate. Gastric bypass patients usually do not absorb vitamins from their food as well and many physicians will use supplements to make sure patients get the nutrients they need to promote health and well being. ...Read more

My legs are bowing. I had gastric bypass surgery 10 years ago. Could this be the cause.

My legs are bowing. I had gastric bypass surgery 10 years ago. Could this be the cause.

No: Bowing of your legs is due, most likely, to arthritis, not to the gastric surgery. Increased weight can cause increased joint wear and changes in your mechanical axis. The weight reduction likely is currently reducing your symptoms, but arthritis and mechanical axis malalignment is common in the general population in your age group. ...Read more

May be hypoglycemia: A possible cause is hypoglycemia. This is often relieved by an appropriate diet. A nutritionist with the bariatric surgery program is the first step. If the problem persists, it could represent pancreatic problems and will need an evaluation by the bariatric surgeon or a gastroenterologist. ...Read more

My veins are really dark and show through out my whole body. Could this be a cause for concern? Have had bad health since gastric bypass surgery!

My veins are really dark and show through out my whole body. Could this be a cause for concern? Have had bad health since gastric bypass surgery!

Weight loss: The veins may be more visible from the weight loss. The benefits of the weight loss however far outweigh the risks of the excess weight. It depends of course how much weight you've lost, when you had the bypass, and your medical conditions. I would suggest you call your surgeon for a follow-up evaluation and see if they have any suggestions. Hope this helps! ...Read more
