Can a vitamin b12 deficiency cause high blood pressure?

I have recently been diagnosed with a vitamin b12 deficiency and have to take injections. Can this deficiency cause me to have high blood pressure? I checked it today and it was 155/89

No, it is highly unlikely that a deficiency of vitamin B12 is causing your high blood pressure problems. High blood pressure is more likely to be due to a high salt diet, high alcohol consumption, stress, or a lifestyle low in exercise.

As for your vitamin deficiency you can find a list of foods high in vitamin B12 here:

Vitamin D deficiency can it lead to diabetes?

ok so my doctor said i have a vitamin d level of 16 when its supposed to be around 50 i was wondering if this could lead to diabetes? (im a 12 year old girl) i have alot of the diabetes symptoms and i tested negative for diabetes in october
my doctor prescribed me to pills and i have enough calcium i just dont get enough sunlight but could this lead to me getting diabetes?

I don't know but it can lead to a lot of things. Bone and teeth malformations for one since your only 12. And a level of 16 is waaaaay too LOW. Buy some vitamin D3 (cholecaciferol) and take at least 2000-3000IU per day for a month or two and retest. You probably have a lot of low calcium symptoms too such as nervousness/tension, cramps, tremors...etc.  (+ info)

How well does the B-12 Vitamin (Dots) work?

I have experienced for a long time now that I have no energy, I have heard alot of people take the B-12 vitamin for this main reason to give them energy. How true is this? And is there any side effects ?

My mom used to force me to take the B-12 dots. Long story short, they didn't work. (There were no side effects though, although it got kinda annoying waiting for them to dissolve sometimes) What did work for me though, was the Emergen-C powder drinks. They are also high in B-12 as well as many other minerals and vitamins. However, it also depends on the person and what is causing the fatigue. I recommend using Emergen-c first (because it's cheaper) and see if it works. If it doesn't, dry the dots.  (+ info)

Can vitamin deficiency play a role in erectile dysfunction?

I was curious to know if erectile dysfunction can be caused by, or in part by vitamin deficiency. Does any doctor know anything about this? How common is erectile dysfunction in young men? (25 and under.)

Yes and no... ED in younger men is a Symptom of something else... get a check up...

What are good natural sources of B-12 vitamin?

I have a slightly elevated cholesterol level.
I have made the switch from Vegetarian to Vegan and plan to spend the time to get all nutritional needs met.
I have heard that walnuts have vitamin B-12.
Any other natural foods or nutritional supplements that you know of for B-12?
Thank you in advance for all thoughtful answers to come!

Congrats on becoming a vegan! No walnuts do not contain b12 neither does most nutritional yeast. Walnuts do contain omega 3 though!

Some good sources of B-12 are fortified cereals, fortified soy/rice milks, meat substitutes/soy analogs, some brands of fortified brewer's & nutritional yeast (such as Red Star & Twinlab). Sea vegetables like seaweed, dried nori, & spirulina, may contain vitamin B12, but their content varies and may be unreliable, lactic acid fermented products such as like tempeh, msio, beer & sauerkraut, but their content as well varies and may be unreliable. Marmite, So Delicious Dairy Free Yogurt, Manging Star foods, and other vegan store bought foods also contains B12 (Cyanocobalamin).

What vitamin deficiency causes fatigue?

I had a blood test for anemia to see why i am tired but i do not have anemia. is there any other vitamin deficiency that causes fatigue?

Hey James,

Despite what your blood test for anemia showed - you may be feeling lethargic due to a drop in your B12. You do not have to be anemic by Western medicine standards to be deficient in vitamin B12.

Vitamin B12 is important to good health. It helps maintain healthy nerve cells and red blood cells, and is also needed to make DNA, the genetic material in all cells.

Characteristic signs of B12 deficiency include fatigue, weakness, nausea, constipation, flatulence (gas), loss of appetite, and weight loss. Deficiency also can lead to neurological changes such as numbness and tingling in the hands and feet. Additional symptoms of B12 deficiency are difficulty in maintaining balance, depression, confusion, poor memory, and soreness of the mouth or tongue.

You may also want to consider the possibility that your blood sugar may be causing your fatique. If your blood sugars are moving up-and-down too quickly fatique can result. If that's the case - you may want to look into eating foods that are lower glycemic. Don't despair - you do not have diabetes. Eating low-glycemic may give you longer-lasting energy calorie-for-calorie, combatting fatique.

If you need some tips on lower glycemic foods -- please feel free to look me up on http://www.TuDiabetes.com - A Community for People Touched by Diabetes.

Can deficiency of Vitamin C lead to the dehydration If yes then Why?

And what is the treatment of deficiency of vitamin C and how much time it takes to get ok

dehydration has an easy fix. Drink water when you are thirsty. You can tell if you are dehydrated by the color of your urine. the darker the color, the more dehydrated you are. your urine should be nearly clear.
Vitamin C has nothing to do with hydration but the lack of it can cause a disease called scurvy  (+ info)

How long does it take Vitamin B-12 to be absorbed into my system?

After research as to my lack of energy lately, I came across a few people who suggested taking Vitamin B-12 as it is responsible for energy metabolisim and I may be deficient. After reading some blogs and the packaging on the actual vitamins I decided to go with the sublingul (under the tongue) form as it is abosrbed into my system faster. I am taking the reccommended dosage once a day and It is working beautifuly although I'm wondering if I am feeling energy when I do because the Vitamin kicks in or if it's a placibo effect. Does anybody know how long it takes to be absorbed...minutes...hours...your response is much appreciated.

Physiology of Absorption, Metabolism, and Excretion

Following ingestion, absorption of thiamin occurs mainly in the jejunum, at lower concentrations as an active, carrier-mediated system involving phosphorylation and at higher concentrations by passive diffusion. Thiamin is transported in blood both in erythrocytes and plasma.

Only a small percentage of a high dose of thiamin is absorbed, and elevated serum values result in active urinary excretion of the vitamin (Davis et al., 1984). After an oral dose of thiamin, peak excretion occurs in about 2 hours, and excretion is nearly complete after 4 hours (Levy and Hewitt, 1971; Morrison and Campbell, 1960). In a study by Davis and colleagues (1984), a 10-mg oral dose of thiamin was given in water, and the mean serum thiamin peaked at 24 nmol/L (7.2 µg/L) —42 percent above baseline. Within 6 hours the serum thiamin concentration had returned to baseline, 17 nmol/L (5.2 µg/L). Prompt urinary excretion of thiamin was also reported by Najjar and Holt (1940) and McAlpine and Hills (1941).

With higher pharmacological levels, namely repetitive 250-mg amounts taken orally and 500 mg given intramuscularly, nearly 1 week was required for steady state plasma concentrations to be reached; a mean elimination half-life of 1.8 days was estimated (Royer-Morrot et al., 1992).

Total thiamin content of the adult human has been estimated to be approximately 30 mg, and the biological half-life of the vitamin is probably in the range of 9 to 18 days (Ariaey-Nejad et al., 1970).
Clinical Effects of Inadequate Intake

Early stages of thiamin deficiency may be accompanied by non-specific symptoms that may be overlooked or easily misinterpreted (Lonsdale and Shamberger, 1980). The clinical signs of deficiency include anorexia; weight loss; mental changes such as apathy, decrease in short-term memory, confusion, and irritability; muscle weakness; and cardiovascular effects such as an enlarged heart (Horwitt et al., 1948; Inouye and Katsura, 1965; Platt, 1967; Williams et al., 1942; Wilson, 1983). In wet beriberi, edema occurs; in dry  (+ info)
