Vitamin B12 Deficiency: Many vitamins and minerals are necessary for our body to function properly. Vitamin B12 is important among them; it is not produced in the body. It is necessary for DNA, red blood cells, and the nervous system. Deficiency can cause fatigue, weakness, mood swings, and affect memory
Our body depends on various vitamins, minerals, and calcium to deal with everyday challenges. The most important of these is vitamin B12, which is not produced in the body on its own and hence it is necessary to take it through animal and plant-based food. Vitamin B12 plays an important role in making our DNA and red blood cells (RBC), strengthening the nervous system, and maintaining the right amount of oxygen in the body. Our daily life and lifestyle such as busy work, lack of sleep, constant screen use and stress, can directly affect this nutrient.
If there is a deficiency of B12, then problems like fatigue, weakness, loss of memory, and mood swings start appearing in the body. Therefore, a proper diet and fulfillment of nutrients is necessary to improve not only health but also lifestyle.
Fatigue and weakness
B12 deficiency first shows up in the form of lack of energy, fatigue, and weakness. Lack of sleep, digestive problems such as diarrhea, constipation and stomach pain are also common. Due to a lack of energy in the body, even daily tasks start to seem difficult.
Affects memory and attention
Vitamin B12 deficiency affects brain function. It causes poor memory, difficulty with attention, and concentration. This can directly affect your daily work and studies.
Mood swings and mental distress
B12 deficiency also affects mood and mental health. Problems like sudden mood swings, irritability, and depression can occur. Long-term B12 deficiency increases mental fatigue and affects the quality of life.
Effects on skin , hair, and nails
Signs of vitamin B12 deficiency are also seen in the skin and hair. This can cause problems like dryness of skin, wrinkles, hair loss, and brittle nails. These early symptoms are a clear indication of nutrient deficiency in the body.
Heart and blood pressure-related problems
B12 deficiency affects the heart and blood pressure. It increases the risk of high blood pressure, heart disease, and stroke. Therefore, if you notice heart-related symptoms, definitely check your B12 level.
neurological and muscle weakness
B12 deficiency can affect hearing and vision. It can also cause problems like muscle weakness, tremors or numbness. These signs indicate that the body is not getting the necessary nutrients.
Lip and Tongue Gestures
If your lips are frequently cracked or your tongue is bitten or painful, this can also be a sign of B12 deficiency. Do not ignore it, as improvement is possible if done early.
How to make up for B12 deficiency
For B12, you can increase the intake of eggs, fish, chicken, milk, and dairy products. Vegetarians can take pulses, soy, nuts, and B12 supplements. Timely fulfillment of nutrients ensures body energy, mental health, and heart protection.
