B6 deficiency is a condition caused by not getting enough of the vitamin B6, also known as pyridoxine. It can lead to anemia and other serious health problems. The most common causes are inadequate intake or absorption of this essential nutrient, increased need due to pregnancy or illness, genetic disorders that interfere with its absorption and metabolism, and certain medications that inhibit its absorption or use in the body.

The signs and symptoms associated with B6 deficiency depend on which organs are affected by the lack of this important vitamin. Commonly reported symptoms include fatigue, depression, confusion, irritability, mouth sores or tongue swelling (glossitis), dermatitis around the eyes (seborrheic dermatitis), peripheral neuropathy (nerve damage) causing numbness in hands/feet/legs/arms/shoulders and lower back pain. In infants it can cause seizures which may lead to developmental delays if left untreated for too long. Other more severe effects include anemia due to reduced red blood cell production (megaloblastic anemia).
There is no specific look associated with B6 deficiency since it does not have any physical characteristics that make it recognizable from other conditions but there are certain factors that may indicate you’re at risk for developing a deficiency such as age over 60 years old; chronic alcoholism; malabsorption syndromes like celiac disease; having had gastric bypass surgery; undergoing dialysis treatments for kidney failure; taking anticonvulsants such as Dilantin®, phenobarbital or primidone; consuming high doses of penicillamine used to treat rheumatoid arthritis. ingesting large amounts of raw egg whites which contain avidin-a protein inhibitor preventing your body from absorbing B vitamins properly.
Since Vitamin B6 plays a key role in many metabolic processes within our bodies it’s important to ensure adequate levels through dietary sources like fish, poultry, fortified cereals, legumes, eggs, potatoes etc. Supplemented when needed via oral tablets available over-the-counter in various strengths depending on individual needs. An easy way to determine if someone might be deficient is asking them about their diet – do they consume foods containing Vitamin B6 regularly? If so then supplementation isn’t necessary however should any signs point towards possible deficiencies further testing might be recommended by a healthcare professional who will run tests including measuring serum concentrations of pyridoxal 5′-phosphate along with assessing clinical presentation / laboratory findings before recommending appropriate treatment plan tailored according each patient’s unique situation.
Dietary Sources of B6
Vitamin B6 is a water-soluble nutrient that the body needs for a variety of functions. It plays an important role in cognitive development and immune function, as well as helping to form hemoglobin and regulating hormones. While B6 can be obtained from supplements, there are also several dietary sources of this essential vitamin.
Certain animal proteins like beef liver, fish, poultry, eggs and dairy products contain large amounts of B6. Plant-based sources include potatoes with skin on, noncitrus fruits such as bananas and avocados, legumes such as beans or lentils and certain nuts like pistachios or walnuts. Fortified cereals are another source of Vitamin B6 found in many grocery stores today.
Consuming foods high in Vitamin B6 is key to ensuring your body gets enough of this essential nutrient each day; however it’s important not to overdo it either since excessive intake can result in nerve damage or other side effects if taken over extended periods of time without medical supervision. To make sure you get just the right amount for optimal health benefits aim for 1-2 mg per day depending on age group – children may need slightly more than adults do – making sure to consult with your doctor before starting any supplementation plan.
Malabsorption and B6 Deficiency
Malabsorption of vitamin B6, or pyridoxine, can lead to a deficiency in this important nutrient. Malabsorption is the inability of your body to properly absorb and process nutrients from food. When malabsorption occurs, it prevents the small intestine from fully absorbing essential vitamins and minerals like vitamin B6 from the foods you eat. This can lead to deficiencies over time if not addressed quickly.
One common cause of malabsorption is an autoimmune disorder called celiac disease that affects the small intestine’s ability to absorb certain vitamins and minerals. Celiac disease causes inflammation in the lining of your small intestine which interferes with its ability to digest and absorb key nutrients including vitamin B6. People who have celiac disease should get tested for a vitamin B6 deficiency as part of their regular health checkups since they are at higher risk for this condition due to their compromised digestive system function.
Another cause of malabsorption related to b6 deficiency is chronic diarrhea or inflammatory bowel diseases such as Crohn’s disease or ulcerative colitis which both affect digestion in different ways but still interfere with proper absorption of dietary nutrition including Vitamin B6 into your bloodstream where it can be used by cells throughout your body for healthy functioning. People who suffer from these conditions should also get tested regularly for a Vitamin B6 deficiency so that any problems can be addressed promptly before symptoms worsen due to prolonged low levels of this vital nutrient in their bodies.
Genetic Disorders & B6 Deficiency
Genetic disorders can often lead to B6 deficiency. For example, homocystinuria is an inherited disorder caused by a mutation in the cystathionine-beta-synthase gene that causes impaired conversion of methionine and other sulfur containing amino acids. This can lead to increased levels of homocysteine in the blood which, if left untreated, can cause damage to vessels leading to stroke and cardiovascular disease as well as numerous other health issues. Some types of anemia are associated with mutations in genes involved in B6 metabolism which may contribute to deficiencies of this vitamin.
Studies have suggested that certain genetic variants may also be associated with decreased absorption or utilization of B6 resulting in lower circulating levels despite adequate dietary intake. The most commonly studied variant is located on chromosome 4q22 and has been linked to increased risk for depression, migraines and seizure disorders due solely or partly attributed to inadequate amounts of Vitamin B6 available for metabolic processes such as neurotransmitter synthesis or energy production within cells.
There are rare inherited conditions known as “hypervitaminosis” where individuals cannot properly metabolize large doses vitamins including Vitamin B6 which could result from defects in enzymes responsible for breaking down these substances into their usable forms within the body – ultimately leading to accumulation and subsequent toxicity rather than deficiency symptoms when too much is consumed at once over time.
Medications that Interfere with B6 Absorption
Medications such as antibiotics, anticonvulsants and diuretics can interfere with vitamin B6 absorption in the body. Taking these medications over a long period of time can increase your risk of developing a deficiency. Antibiotics are known to reduce the amount of Vitamin B6 that is absorbed from food by disrupting normal gut bacteria.
Anticonvulsants, which are drugs used to treat seizures, may lead to decreased levels of vitamin B6 in the body due to their effect on certain enzymes involved in its metabolism. Diuretics also affect how much vitamin B6 is available for use by the body, as they promote increased urination which results in loss of nutrients like vitamins and minerals from the urine.
In some cases, taking supplemental forms of vitamin B6 may be necessary if an individual is on any medication that interferes with absorption or utilization of this nutrient. Talk to your healthcare provider about what dose would be appropriate for you based on your medical history and current medications.
Liver Disease & Reduced B6 Levels
Liver disease can have a major impact on b6 levels in the body. Liver diseases such as cirrhosis and fatty liver can lead to reduced absorption of B vitamins, including b6. This is due to the fact that many of these conditions cause damage to the small intestine and reduce its ability to absorb nutrients from food. Some drugs used to treat liver disease may also interfere with vitamin B6 absorption or metabolism. As a result, individuals with chronic liver disease are at risk for developing low levels of vitamin B6 in their bodies even if they consume adequate amounts of this nutrient through diet or supplementation.
Alcoholism is another common cause of decreased Vitamin B6 levels in the body since it has been associated with both impaired intestinal absorption and metabolic changes which limit uptake into cells. Alcohol consumption has been linked to increased excretion of certain forms of vitamin B6 from the body resulting in lower overall concentrations in blood plasma than what would be expected based on dietary intake alone. Alcoholics tend to eat diets that are deficient in essential nutrients like b-vitamins so this can further contribute towards low concentrations within tissues over time if not addressed properly by medical intervention or lifestyle modifications.
Kidney Failure & Vitamin B6 Loss
Kidney failure is one of the most common causes of B6 deficiency. The kidneys are responsible for regulating Vitamin B6 levels, and when they fail to do so, a deficiency can occur. When this happens, there are two main sources of loss: firstly, the inability to absorb enough Vitamin B6 from dietary sources; secondly, an increased excretion rate due to renal dysfunction or damage.
When kidney function declines and the kidneys cannot effectively filter waste products out of the body, they can also start to filter out more vitamin B6 than normal. This results in lower levels circulating in the blood and consequently leads to a deficiency. Damaged or diseased kidneys may not be able to reabsorb as much vitamin B6 from urine before it is eliminated from your body; thus leading to further losses.
Certain medications used for treating kidney problems such as diuretics can also increase urinary excretion rates which lead to greater losses of Vitamin B6 in individuals with impaired kidney function. As such it’s important that those suffering from chronic renal impairment receive proper medical advice on how best manage their health condition while reducing any associated risk factors like Vitamin B6 deficiencies.
