Vitamin B12 is important in supporting brain function and helping your body produce red blood cells.

Without enough B12, you may feel fatigued or experience other physical symptoms. This article will explore what causes vitamin B12 deficiency, its symptoms, and related risk factors. So, let's get into the details and see how to overcome this deficiency and keep your body and mind healthy!

What Is Vitamin B12 Deficiency? 

Vitamin B12 is a water-soluble vitamin important for making red blood cells and keeping the nervous system working properly. It is required for DNA synthesis and stability, nerve health, and red blood cell production. It is mainly found in animal-based foods like meat, beef, dairy, and eggs. Plant-based foods don't provide enough of this vitamin.

People who follow strict vegetarian or vegan diets may not get enough Vitamin B12. Not having enough B12 can lead to health problems and vitamin B12 deficiency. Without enough Vitamin B12, the body struggles to function properly, and it can cause serious issues like fatigue, weakness, and more serious complications.

Over time, a deficiency can result in Vitamin B12 deficiency neurological symptoms, such as numbness, tingling, and memory problems. It can cause lasting damage to the nervous system if you do not treat it properly. Proper intake of B12 is very important for maintaining energy levels, brain function, and overall health. Eating Vitamin B12-rich foods like meat, dairy, and eggs is important to keep your body healthy.

What Are The Causes Of Vitamin B12 Deficiency? 

There are different causes of vitamin B12 deficiency. It is very important to understand the causes to prevent and treat this condition:

Cause 1: Not Consuming Enough Vitamin B12 In The Diet

One of the main causes of Vitamin B12 deficiency is not getting enough of this important vitamin from your diet. Since Vitamin B12 is mainly found in animal products, vegetarians and vegans are at a higher risk of deficiency. Foods like beef, fish, dairy, and eggs are rich in Vitamin B12; not eating enough can lead to health problems. If you are not getting enough food, taking Vitamin B12 supplements can help meet your daily needs and keep your body healthy.

Cause 2: Gastritis

Gastritis happens when the lining of your stomach becomes swollen or irritated. This condition can make it hard for the stomach to absorb important nutrients from food, including Vitamin B12. Bacterial infections or certain medications, like painkillers, often cause gastritis. Over time, this swelling can lead to poor nutrient absorption, which can cause Vitamin B12 deficiency. It can lead to other health problems if you do not treat it promptly. Taking care of your stomach health and getting the right treatment for gastritis is important to ensure your body absorbs the nutrients it needs.

Cause 3: Surgery

In some cases, surgeries can affect the body's ability to absorb Vitamin B12. For example, weight loss surgeries often reduce the stomach's capacity to absorb nutrients like B12. Similarly, people who have had surgery on their small intestine may struggle to absorb enough B12. These surgeries can lead to a higher risk of Vitamin B12 deficiency, which may cause health problems if not properly managed. It is important for those who have had such surgeries to keep track of their B12 levels and consider supplements to deal with deficiency.

What are Vitamin B12 Deficiency Symptoms? 

Recognizing the symptoms of Vitamin B12 deficiency is important for early diagnosis and proper treatment. Here are the symptoms of Vitamin B12. 

1. Physical Symptoms: The common physical symptoms of Vitamin B12 deficiency are fatigue, weakness, and dizziness. People may feel unusually tired even after proper rest. Other common symptoms are pale skin, shortness of breath, and a sore tongue.
2. Neurological Symptoms: Neurological symptoms can include tingling or numbness in the hands and feet. People often notice symptoms like balance issues and muscle weakness. If the deficiency is not treated well, it can damage the nervous system. Damaged nervous systems can cause problems with walking and coordination. Memory loss and confusion can occur in extreme cases, especially in older adults.
3. Psychological Symptoms: A Vitamin B12 deficiency can also cause some psychological symptoms. Some common symptoms are depression, irritability, and mood swings. Some people may experience difficulty concentrating on simple tasks. In some severe cases, people also experience hallucinations.

How To Treat Vitamin B12 Deficiency? 

Treatment for Vitamin B12 deficiency can be different because it depends on the condition and its cause. For example:

• Minor Deficiency: If you have a minor deficiency, you should increase your intake of foods rich in Vitamin B12, such as fatty fish, fortified milk, fortified cereals, yogurt, beef liver, and egg yolks.
• Severe Deficiency: For people with severe deficiency and conditions like pernicious anemia, B12 injections are important to ensure proper absorption. Stronger doses (up to 50,000 IU) are also suggested for them.

Most people need lifelong treatment to prevent recurring vitamin deficiencies. B12 supplements are available in oral form, tablets, or injections. Your healthcare provider will recommend the best solutions based on your specific needs.

Vitamin B12 Deficiency: Risk Factors

Some people are at a higher risk of developing Vitamin B12 deficiency. Understanding these risk factors will help you take the right step.

• Being Older: The ability to absorb Vitamin B12 naturally decreases in older people, especially after age 75. Older adults are more likely to develop diseases related to Vitamin B12. For this reason, older people should have their B12 levels checked regularly.
• Taking Certain Medications: Some medications interfere with B12 absorption, which can cause a deficiency. For example, the medicine used to reduce stomach acid production can cause a deficiency of Vitamin B12, as stomach acid is required for its absorption.  
• Having a Digestive System Disorder: Conditions that affect the digestive system, such as Crohn's disease or celiac disease, can interfere with the absorption of Vitamin B12. People with these conditions must take B12 supplementation regularly to maintain healthy levels.

Conclusion:

Vitamin B12 deficiency can cause many problems if you don't treat it properly. It can affect everything from energy levels to brain function and nerve health. The deficiency can be caused by various reasons, like not consuming enough B12, digestive issues, or specific health conditions. Early detection and treatment can prevent long-term damage. Adding more Vitamin B12-rich foods or supplements can help maintain healthy B12 levels. If you are experiencing any Vitamin B12 deficiency symptoms, you should consult the healthcare provider for proper diagnosis and treatment.
