I don’t know if you are aware, but vitamin B12 is pretty vital to your health. Check out what happens to your body if you lack this important vitamin.
7 signs that show extremely low B12 levels
Vitamin B12, which is also known as cobalamin, is an essential nutrient that plays a vital role in several bodily functions. It is essential for the production of red blood cells, maintaining a healthy nervous system, and synthesizing DNA. Since our bodies cannot produce vitamin B12 on their own, we must obtain it through our diet or supplements.
Normal vitamin B12 levels range above 300 pg/mL. If the vitamin B12 level is less than 200 pg/mL, it is considered deficient. A significant drop in vitamin B12 levels can lead to a condition called vitamin B12 deficiency. If left untreated, this deficiency can have severe health consequences.
Fatigue and weakness
Vitamin B12 deficiency is a medical condition that arises when the body doesn’t have enough vitamin B12 to function properly. One of the most common and early signs of this deficiency is fatigue and weakness.
Vitamin B12 is an essential nutrient that plays a crucial role in the production of red blood cells.
Red blood cells carry oxygen throughout the body, and without enough of them, tissues and organs do not receive an adequate oxygen supply, leading to fatigue and weakness.
Individuals with low levels of vitamin B12 often describe feeling tired, sluggish, and lacking energy, even after getting a full night’s sleep.
In addition to fatigue and weakness, vitamin B12 deficiency can lead to other symptoms such as numbness or tingling in the hands and feet, difficulty walking, memory problems, depression, and even dementia in severe cases. It’s essential to recognize the early signs of vitamin B12 deficiency and take corrective measures to prevent further complications.
Cognitive decline
Vitamin B12 plays a vital role in maintaining a healthy nervous system, including the brain.
Low levels of B12 can negatively affect cognitive functions, leading to concentration difficulties, memory problems, and mental fogginess. In severe cases, it may even result in mood disturbances, such as depression and irritability. These cognitive impairments can significantly impact daily life and overall well-being, making it crucial to address B12 deficiency promptly.
Sensations of numbness and tingling
Extremely low levels of vitamin B12 can cause numbness and tingling sensations, especially in the hands and feet. This condition is known as peripheral neuropathy and occurs because B12 deficiency can damage the myelin sheath surrounding nerves.
As a result, nerves cannot transmit signals properly, leading to feelings of tingling, burning, or numbness. If left untreated, this can progress to more severe symptoms such as muscle weakness and difficulties with balance and coordination.
Vision issues
Vitamin B12 deficiency can cause vision problems in some cases. When the level of B12 is low, optic neuropathy may occur, which damages the optic nerve.
As a result, the vision can become blurred or disturbed, making it difficult to distinguish colors, and in severe cases, there can even be vision loss. Although it is not a common symptom, this highlights the importance of promptly addressing B12 deficiency to prevent further complications.
Mouth ulcers
Low levels of vitamin B12 in the body can lead to oral symptoms, such as glossitis – an inflammation of the tongue that makes it appear swollen, red, and shiny.
Mouth ulcers or canker sores may also develop, causing pain and discomfort while eating or speaking. These oral symptoms can be some of the early signs of a B12 deficiency.
Difficulty walking and balance issues
As the condition of vitamin B12 deficiency worsens, it can cause neurological symptoms that affect balance and mobility. This is due to the damage caused to the nerves that control muscle movement and coordination. Individuals who suffer from severe B12 deficiency may experience muscle weakness, difficulty walking and an unsteady gait, which makes them more likely to fall or get injured.
Pale skin
Vitamin B12 deficiency can cause changes in the skin’s appearance, leading to a pale or yellowish hue, also known as megaloblastic anemia. This occurs when the red blood cells, produced in the absence of enough B12, become abnormally large and fragile, resulting in their early breakdown and a decrease in the number of healthy red blood cells in circulation.
It is generally safe to consume vitamin B12 in excess as it is a water-soluble vitamin, and any extra amounts are excreted in the urine.
However, high doses can lead to side effects such as mild diarrhea, skin rashes, and itching. Extremely high doses may cause dizziness, headaches, and nerve problems, so it is crucial to consult a healthcare provider before taking excessive amounts. This is particularly important for individuals without a medically diagnosed deficiency, as it can interact with certain medications and potentially mask underlying health issues.
