No: B12 injections would not interfere with weight loss. You may need to reduce you intake of food more than you have done. Have a diet rich in fresh vegetables, fruits, whole grains, low fat milk and milk products, nuts, beans, legumes, lentils and small amounts of lean meats. Avoid saturated fats. Exercise at least 150 minutes/week and increase the intensity of exercise gradually. Do not use tobacco or alcohol in any form. ...Read more

Are vitamin B6 and B12 shots good for weight loss?

No effect expected: Shots of vitamins b6, b12, or other vitamins should not have an effect on one's weight. The only way for a normal, overweight person to lose weight is to eat fewer calories than he uses up each day. His body will burn up fat to get the additional needed calories that he himself is not eating. ...Read more

I saw a weight loss doctor, and she said it was a B12 injection that was administered in my stomach. Since then I have experienced spasms.

That's strange: I do not know of any reason to administer B12 via an injection into your abdomen. I would recommend seeing your regular physician to determine what may be causing your spasms, and whether or not you even need B12 injections. ...Read more

What are all the differences between hCG used in weight loss clinics combined w/ B12 &the hCG used to treat fertility?

Will me taking the b12&hcg weight loss injection effect my lab work? I go in 3 weeks for blood work.

Yes: If they are checking to see if you are pregnant it might give false positive. It might give you an elevated triglyceride level since the body is using your fat as fuel. Also, your ph may be low since the diet induces ketosis. Best to tell them you are on the diet and it may affect your labs. ...Read more

What are reasons for an elevated MCV 101.6fl and elevated B12 1345pg/ml. I eat meat maybe once a week. I'm 5'5" 118lb have fatigue and weight loss.

Inadequate digestion: I should start by saying that it is possible to be deficient in vitamin B12 even with an elevated blood test. Common causes of an elevated MCV are inadequate absorption of vitamins in your gastrointestinal tract, excess alcohol intake and other medications. If you have a normal diet it may be advisable to have additional blood work performed to ensure that you are adequately digesting nutrients. ...Read more

I hope so: If he monitors your progress and counsels you on weight loss with exercise and proper diet as well, it sounds as though it is fine, as witnessed as people losing weight "weight clinics" such as this aren't always about the shots you get, but more about being motivated to lose and do as instructed, especially since your probably paying for it, you want to assure you are getting your monies worth. ...Read more

Unintentional weight loss. Low iron levels low b12 and folate (folic acid). Can't get answers.?

Wt loss, low iron: Could be from a vast number of possibilities. This question requires more information. A good history, physical exam and scrutiny of current, past and future bloodwork will all help piece together this puzzle. In general low iron in healthy premenopausal women is usually from menstruation or pregnancy. The weight loss is somewhat worrisome. Highly recommend a formal consultation with a doctor. ...Read more

If I take the b12&hcg injection for weight loss (1/2cc hcg)in shot. Will that increase fertility or is it safe with 1250 calorie diet?

No: The HCG does not affect your fertility at the recommended doses for the diet, 125 iu. And you should be on the original protocol which is 500 calories for it to be effective. Too many phsyicians have modified the diet and dose and still claim the results will be the same. They won't! the weight loss will lead to fertility as it changes the estrogen to Progesterone balance. ...Read more

Hair & weight loss, fatigue. Thyriod, iron and B12 normal. Had a baby 12mths ago. What could be causing it?

Thyroid, adrenal: Everything about this screams thyroid. Thyroid problems commonly develop in pregnancy. When you say "thyroid normal" I bet it means a "normal" tsh. This is meaningless in ruling out thyroid problems. You need a free t3 (liothyronine), (liothyronine) reverse t3 (liothyronine) ; thyroid antibodies ; a doctor who already knows this (as most holistic docs do)! see http://bit. Ly/1bogdxh ; http://bit.

Nerve impingement: The legs and low back can be involved w/nerve impingement because the nerve gives feeling to those areas. So, depending on what nerve (s) are trapped, that pathway will experience pain. Glad you B 12 is now good. Ask doc or a natural doc about high dose Alpha Lipoic Acid which can help w/nerve issues.

A verterinarian told me they give B12 injections to animals to gain weight? Why then are B12 injections given to lose weight in humans?

No wt loss w/B12: I can't speak for veterinary medicine as I am not a veterinarian. However, as a family physician, I can assure you that I don't give B12 injections to cause weight loss in humans as there is no such link between the two. In other words, taking B12 whether as a shot or pill will not lead to weight loss. If you're low in b12, you may need B12 pills or shots, but that won't cause weight loss. ...Read more
