Vitamin B12 is crucial for many functions in your body. It’s necessary for maintaining healthy nerve cells, aiding in the production of DNA and RNA, working with other B vitamins to form red blood cells, aiding in iron function, and improving mood regulation, among other functions. Here are some symptoms and complications that may occur if you don’t get enough Vitamin B12:
Physical Symptoms
- Fatigue and Weakness: A decrease in red blood cell production can result in fatigue.
- Constipation: Gastrointestinal problems like constipation can occur.
- Loss of Appetite and Weight Loss: This can occur along with gastrointestinal symptoms.
- Numbness and Tingling: Insufficient B12 can lead to poor nerve functioning.
- Poor Memory or Cognitive Functions: Especially in elderly people, low B12 levels can lead to poor cognitive function.
- Vision Problems: In extreme deficiency cases, damage to the optic nerve can occur.
Neurological Symptoms
- Depression: Due to its role in mood regulation, deficiency can lead to depression.
- Irritability and Mood Swings: Can occur because of the influence on neurotransmitter and hormone production.
Long-term Complications
- Pernicious Anemia: A severe form of anemia that can result in neurological issues.
- High Levels of Homocysteine: Which can increase the risk of heart diseases.
- Neurological Damage: Irreversible in severe cases.
- Pregnancy Complications: Such as neural tube defects.
If you’re mostly plant-based in your eating habits, it’s particularly important to be aware of your B12 intake, as the vitamin is primarily found in animal products. Supplements or fortified foods can provide the necessary amounts. Always consult healthcare professionals for accurate diagnosis and appropriate management.
