A B12 deficiency may also cause diarrhea, nausea, constipation, bloating, gas, and other gastrointestinal symptoms ( 2 , 19 ). These issues can affect both adults and children ( 2 , 20 ).
You may be deficient in a key mineral or vitamin.
The most common nutrient deficiencies that are linked to bloating are zinc, magnesium, molybdenum and thiamin.
People with vitamin B12 deficiency can have neurological symptoms and/or damage without anemia (lack of red blood cells). General physical symptoms of vitamin B12 deficiency can include: Feeling very tired or weak. Experiencing nausea, vomiting or diarrhea.
People with vitamin B12 deficiency are likely to experience a wide range of symptoms, though weight gain is unlikely one of them.
A Vitamin B12 deficiency can lead to long-term weight control problems. When the body's natural balance is disrupted, it typically responds by slowing down your metabolism, conserving fat stores, and burning fewer calories throughout the day.
B-complex vitamins: These help metabolize carbohydrates, fats, and proteins, activating stored energy instead of letting it turn to fat. Niacin, vitamin B-6, and iron: This impressive trio increases your body's production of the amino acid L-carnitine to help burn fat.
A lack of vitamin B12 can cause neurological problems, which affect your nervous system, such as: vision problems. memory loss. pins and needles (paraesthesia)
Once you begin treating your vitamin B12 deficiency, it can take up to six to 12 months to fully recover. It is also common to not experience any improvement during the first few months of treatment. If you can, it's a good idea to address what's causing the deficiency.
A lack of B12 may lead to depression, confusion, memory problems, and dementia. It also can affect your balance. B12 supplements are usually safe.
Conclusions: Vitamin B12 supplementation does not alter the gut microbiota composition under healthy conditions, but does contribute to differential microbial responses and intestinal dysbiosis following the induction of experimental colitis.
Vitamin B-12 deficiency can affect the digestive tract. A lack of red blood cells means that not enough oxygen reaches the gut. Insufficient oxygen here may lead to a person both feeling and being sick. It may also cause diarrhea.
Evidence suggests that vitamin B-12 may be associated with changes in bacterial abundance. While results from in vitro studies suggest that vitamin B-12 may increase alpha-diversity and shift gut microbiome composition (beta-diversity), findings from animal studies and observational human studies were heterogeneous.
It might be as simple as eating too much too fast, or you could have a food intolerance or other condition that causes gas and digestive contents to build up. Your menstrual cycle is another common cause of temporary bloating. Sometimes a bloated stomach can indicate a more serious medical condition.
If you show up at the doctor's office looking pale, especially around the eyes, and complaining of constant chills and exhaustion, your doctor is likely to test for iron deficiency. Other symptoms include bruising, dry skin and a bloated feeling.
It is not uncommon for an iron deficiency to present alongside uncomfortable gut symptoms like gas and bloating, constipation, diarrhea, and abdominal pain. And while there is no evidence that supports that low iron levels directly cause GI symptoms, iron deficiency can often result from digestive disorders.
Diet. Some people can develop a vitamin B12 deficiency as a result of not getting enough vitamin B12 from their diet. A diet that includes meat, fish and dairy products usually provides enough vitamin B12, but people who do not regularly eat these foods can become deficient.
Bananas also contain fibre and potassium. It helps manage blood pressure, reduce stress, and relieve constipation and ulcer problems. The fruit also helps regulate body temperature. Another fruit that is rich in vitamin B12 is blueberries.
A serum B12 above 300 pg/mL is interpreted as normal. Patients with B12 levels between 200 and 300 pg/mL are considered borderline, and further enzymatic testing may be helpful in diagnosis. Patients with B12 levels below 200 pg/mL are considered deficient.
Anemia may not develop until 3 to 5 years after the deficiency begins because a large amount of vitamin B12 is stored in the liver.
There's no solid proof that vitamin B-12 shots, also called injections, help you lose weight. Vitamin B-12 is a water-soluble B complex vitamin. It's found naturally in many foods, such as meat, fish and dairy products. Vitamin B-12 is added to some foods and is available as a dietary supplement.
Low intake of vitamin B-12 also affects your digestive tract -- a severe deficiency paralyzes the muscle tissue in the lining of your digestive tract, hindering intestinal function.
