5 Unusual Signs of Vitamin B12 Deficiency in Women: What You Need to Know

Why Vitamin B12 Is Important

Vitamin B12, also known as cobalamin, is essential for making red blood cells, supporting brain function, and helping with DNA formation. A shortage of this nutrient in women can seriously affect their health—especially during pregnancy, breastfeeding, or due to poor dietary intake. If left untreated, this condition may lead to nerve damage and complications during pregnancy.

Common and Overlooked Symptoms in Women

The signs of B12 deficiency often develop slowly, making it easy to ignore them until they become serious. One of the earliest symptoms is constant tiredness that doesn’t go away even after resting. Women may also feel tingling or numbness in their hands and feet.

Other surprising symptoms include a sore or swollen tongue, mouth ulcers, memory problems, mood swings, or feelings of depression. In more advanced cases, it can cause difficulty walking or muscle weakness in the hips and legs.

Additional warning signs may include pale skin, constipation, infertility, shortness of breath, and heart palpitations. In pregnant or breastfeeding women, low B12 levels may result in anaemia or poor growth in babies due to insufficient nutrient supply.

What Causes B12 Deficiency

One of the main reasons women suffer from low B12 levels is due to diet—especially those who follow vegetarian or vegan lifestyles. Since B12 is found mostly in animal products like meat, eggs, and dairy, not consuming these foods regularly increases the risk.

Some medical conditions also block the body’s ability to absorb B12 properly. These include autoimmune disorders, intestinal problems like Crohn’s disease, or previous stomach surgeries such as gastric bypass. Certain medications used for diabetes or stomach issues may also interfere with B12 absorption.

The need for B12 increases during pregnancy and breastfeeding. Without proper intake, the body’s stored levels may run low. In older women, reduced stomach acid levels can prevent the body from extracting B12 from food, making them more vulnerable.

How to Treat and Prevent It

Thankfully, B12 deficiency is treatable. A blood test can confirm your levels and help determine the right approach. In severe cases, doctors may suggest regular B12 injections, especially if absorption is a problem. For milder conditions, oral supplements or nasal sprays can be effective.

To prevent deficiency, include B12-rich foods in your diet—such as fish, poultry, dairy, and fortified cereals. For those avoiding animal products, daily supplements are recommended. The average adult needs about 2.4 micrograms of B12 daily, while pregnant or breastfeeding women may need slightly more.

Regular health check-ups are key, especially for women in high-risk groups. Early detection makes a big difference, as nerve-related symptoms may be reversible with timely treatment.
