Understanding Folic Acid Deficiency: Causes, Symptoms, and Treatment

September 12, 2024

Folate, also referred to as vitamin B-9, helps the body to create red blood cells and further cell growth. A folate deficiency, if not checked in time, can have serious consequences. The effects can impact our overall health, from chronic weakness to brain fog, patchy memory, or folic acid deficiency anemia. However, with a well-balanced diet and a healthy lifestyle, one can maintain good folate levels. In this blog, we explore the causes, symptoms, and treatments that should be taken in case of folic acid deficiency.

Folic Acid Deficiency Causes

Folate deficiency can happen for many reasons. Here are the major ones.

Poor Diet

Diet plays a key role in maintaining the folic acid levels in our body. Folate levels can drop within a few days if folate-rich foods are not taken consistently. Here are some essential sources of folate:

Vegetables: green leafy vegetables like spinach and asparagus, avocado, peas, cauliflower, and broccoli.
Fruits: especially citrus like oranges, kiwi, grapes
Fortified cereals and grains: enriched breads, pasta.
Lentils, chickpeas, beans, and eggs are also extremely beneficial.

Another important factor is to eat fresh, lightly cooked meals instead of over-cooked foods. Extensive cooking destroys the folate in our food. Additionally, including zinc-rich foods in your diet can support overall nutrient absorption, including folate.

Malabsorption

At times, even if a person is taking a balanced diet, folate deficiency symptoms may arise. This could be because of an impaired absorption in the gastrointestinal tract, which could be due to certain underlying health conditions. These are health issues like Crohn’s disease, celiac disease, short bowel syndrome, amyloidosis, or mesenteric vascular insufficiency. Due to pre-existing health conditions, folate absorption may not occur from the food intake, leading to a deficiency.

Increased Need

An increased need for folate occurs during pregnancy or in women who are planning to conceive. During pregnancy, the daily requirement for folate has been recommended at 600 mg, instead of the usual 400 mg. Breastfeeding mothers are also advised to increase their iron intake to avoid folic acid deficiency symptoms.

In certain cases, patients undergoing dialysis due to diabetes may also have an increased need for folate. If an expecting mother does not meet the folate requirement, there is a higher chance of development issues in the baby.

Medications

Certain medicines may interfere with folic absorption in the body, such as:

Medicines used to treat ulcerative colitis
Methotrexate: used for cancer treatment and rheumatoid arthritis
Metformin: used in case of diabetic patients
Trimethoprim-sulfamethoxazole, an antibiotic.
Antiseizure medication such as phenytoin, phenobarbital

These drugs can inhibit folate utilisation, or its conversion, leading to a folate deficiency.

Genetic Factors

Genetic factors can also contribute to folic acid deficiency symptoms. These are:

MTHFR gene mutations: This gene gives instructions to the body for making an enzyme for folate metabolism. However, variations in this gene can inhibit the body from converting folate into an active form.
Hereditary Folate Malabsorption: This is a rare genetic condition. In this case, the body does not have the ability to absorb folate from food, leading to folate deficiency.
Environmental and lifestyle factors such as alcohol consumption can also impair folate absorption.

Folic Acid Deficiency Symptoms

Here are the folate deficiency symptoms you should keep a note of.

Fatigue

A person may feel extremely tired all the time and be lacking energy. This can be despite sleeping for a sufficient number of hours.

Anaemia

A poor level of healthy red blood cells causes folic acid deficiency anemia. In this condition, there may not be enough RBC for carrying oxygen to the body's tissues. This results in a low level of oxygen in the entire body, leading to issues like fatigue, weakness, and shortness of breath.

Cognitive Issues

A serious outcome of folic acid deficiency is in the form of cognitive issues like poor concentration, depression, irritability, insomnia, cognitive decline, and, in extreme cases, psychosis. Consistent poor folate levels can also cause memory loss or dementia.

Mouth Sores

Mouth ulcers may be caused by vitamin deficiencies, including low folate levels. A

severe deficiency may result in a red and sore tongue. Check out our blog on the Top 11 Vitamin-Rich Foods List

Growth Problems

A lack of folate deficiency can also affect the foetus. Folate is important for the foetus’s brain development and spinal cord development. A deficiency can cause neural tube defects, like spina bifida and anencephaly in the baby.

This can later affect learning abilities, behavior, and cognitive development. Further, the child may also suffer from stunted growth or delayed development due to inadequate folate at the initial stages. Lastly, immunity may also be impacted due to this deficiency. The child may have low resistance and get frequent infections, which would later impact his development.

Folic Acid Deficiency Treatment

Dietary Changes

Your diet needs an overhaul in case you are folate deficient. You should try to include foods from all major food groups in your diet to ensure they are well-balanced. The essentials which should be included are dark green, leafy vegetables (kale, spinach, broccoli, asparagus, etc) and citrus fruits like oranges, kiwi, and grapes. These foods are rich in iron, and regular consumption can increase folic acid levels. One must include fortified cereals and whole grains. Fresh, lightly cooked food should be consumed instead of deep-fried or overcooked food.

Supplements

One should consult a doctor before taking any supplement as a folic acid deficiency treatment. On a routine blood test, if a folate deficiency is observed, the medical practitioner will usually recommend folic acid tablets. These are usually prescribed for daily usage, up to 4 months, to build up the folate. However, only the intake of supplements is not sufficient, once one has to make dietary changes to improve their folate levels.

Addressing Underlying Conditions

While addressing the issue of low iron levels in the body, one must consider certain other factors as well. A poor diet, regular alcohol consumption, or the intake of drugs can severely impact the body. Further, patients on specialized medications such as methotrexate, phenytoin, and trimethoprim can suffer from this deficiency. The doctor should also check for a B-12 deficiency, as most symptoms overlap with a folate deficiency.

The underlying issues should be sorted out before any new interventions occur.

Medication

The doctor may recommend an oral folic acid tablet (1-5 mg) daily to treat folic acid deficiency symptoms. In case the B-12 is found to be lacking, the doctor may suggest a B-12 supplement as well.

Regular Monitoring

This is essential and the doctor would suggest the time duration after which a laboratory test should be done. Parameters such as the complete blood count, folate, and vitamin B-12 levels, among others should be checked. Always check with your doctor for the required tests.

Conclusion

Folate deficiency can have a deep impact on a person’s overall health. One should watch for symptoms such as unusual tiredness, pale skin, or dizziness, as these could be indicators of a folic acid deficiency. A regular, healthy diet intake is the best way to fortify oneself. Routine health checks are essential and should be done.
