What is Folate Deficiency?
Written by Medicover Team and Medically Reviewed by Dr K Pradeep Bhaskar , Oncologists
Folate Deficiency is a condition where the body lacks sufficient folate (vitamin B9), which is essential for producing red blood cells and facilitating DNA synthesis. It primarily affects the blood and nervous systems, leading to anaemia, fatigue, and neurological issues.
What are the Folate Deficiency Symptoms and Warning Signs?
Folate deficiency can develop quietly, but its effects can impact your energy, mood, and overall health. Symptoms that appear early help facilitate timely diagnosis and treatment. Below is a list of common and severe symptoms associated with low folate levels.
Common Symptoms
- Persistent fatigue or low energy
- Pale skin
- Irritability or mood changes
- Poor appetite
- Mouth sores or a swollen tongue
- Difficulty concentrating or brain fog
Severe Symptoms
- Shortness of breath with mild exertion
- Rapid heartbeat
- Tingling or numbness in hands and feet
- Memory problems or confusion
- Developmental delays in children
- Growth issues during pregnancy
What are the Different Types of Folate Deficiency?
While folate deficiency typically refers to low levels of folate in the body, it can be classified based on its cause or context:
- Dietary Folate Deficiency: Caused by inadequate intake of folate-rich foods such as leafy greens, legumes, and citrus fruits.
- Malabsorptive Folate Deficiency: Occurs when the body can't absorb folate properly, as seen in conditions like celiac disease or inflammatory bowel disease.
- Increased Requirement for Folate Deficiency: This occurs during pregnancy, growth spurts, or chronic illnesses, where the body's demand for folate increases.
- Medication-Induced Folate Deficiency: Certain drugs (e.g., methotrexate, phenytoin) interfere with folate absorption or metabolism.
- Alcohol-Related Folate Deficiency: Chronic alcohol use can impair folate absorption and increase its loss from the body.
What are the Common Causes and Risk Factors of Folate Deficiency?
Folate deficiency develops when the body doesn't get or absorb enough folate (vitamin B9), affecting red blood cell production and nervous system function. Understanding what triggers this condition and who is most susceptible to it can help prevent long-term health issues.
Causes of Folate Deficiency
These are direct medical or physiological reasons that reduce folate levels in the body:
- Poor dietary intake: Not eating enough folate-rich foods like leafy greens, citrus fruits, and beans
- Malabsorption disorders: Conditions like celiac disease, Crohn's disease, or tropical sprue interfere with folate absorption.
- Increased demand: Pregnancy, infancy, adolescence, and certain illnesses increase folate needs
- Medication interference: Drugs such as methotrexate, sulfasalazine, or anticonvulsants can block folate metabolism
- Chronic alcohol use: Alcohol impairs both folate absorption and storage
Risk Factors for Folate Deficiency
These factors increase the likelihood of developing a deficiency but do not directly cause it:
- Age (elderly or infants): Nutrient needs change, or absorption may decline with age
- Pregnancy: Higher demand makes pregnant individuals more vulnerable
- Poor dietary habits: Diets low in fruits and vegetables increase the risk
- Smoking: Affects nutrient absorption and folate metabolism
- Liver disease: The liver stores folate; damage can lower available levels
- Low socioeconomic status: Limited access to nutritious food can contribute to poor folate intake

Get Second OpinionHow is Folate Deficiency Diagnosed?
Folate deficiency can often go unnoticed until symptoms such as fatigue, pale skin, or mouth sores begin to interfere with daily life. Accurate diagnosis is crucial for understanding the severity and underlying cause. At Medicover, advanced diagnostic services help identify and manage folate deficiency with precision and care.
Common Diagnostic Procedures
- Complete Blood Count (CBC): Detects anaemia by evaluating red blood cell size and count.
- Serum Folate Test: Measures the level of folate in the blood to confirm deficiency.
- Red Blood Cell (RBC) Folate Test: Offers a more stable measure of folate status over time.
- Vitamin B12 Test: Often conducted in conjunction with folate testing, as symptoms can overlap.
- Homocysteine Test: Elevated levels may indicate low levels of folate or vitamin B12.

- Parenteral Folate (Injection): Used in cases of severe malabsorption or when oral intake is not possible.
- Vitamin B12 Supplementation: Given alongside folate if coexisting B12 deficiency is suspected, to avoid neurological complications.
- Duration: Improvements often begin within a few days; full correction may take 4-6 weeks, depending on severity.
Dietary Modifications and Nutritional Counselling
- Folate-Rich Foods: Incorporating dark leafy greens, citrus fruits, beans, and fortified cereals.
- Dietitian Support at Medicover: Specific nutrition plans help meet daily folate needs and address underlying causes, such as a poor diet or alcohol use.
Treatment of Underlying Conditions
- Gastrointestinal Disorders: Managing conditions like celiac disease or Crohn's to improve folate absorption.
- Medication Review: Adjusting or replacing folate-interfering drugs under medical supervision.
- Pregnancy Support: Folate supplementation is routinely advised before conception and during pregnancy to prevent neural tube defects.
Follow-Up and Monitoring
- Repeat Blood Tests: CBC and folate levels are rechecked within 4-8 weeks to ensure recovery.
- Symptom Monitoring: Patients are assessed for improvements in fatigue, anaemia, or cognitive symptoms.
- Ongoing Preventive Care: This is especially important for individuals with chronic illnesses or dietary restrictions.

When to See a Doctor?
If you've been feeling unusually tired, struggling with concentration, or noticing pale skin and mouth sores that don't go away, it might be time to consult a doctor.
Folate deficiency can be subtle in the beginning, but untreated, it may lead to serious complications like anaemia or nerve-related problems.
Know the Right Time to Seek Medical Help
- Persistent Symptoms: If fatigue, weakness, or digestive issues like loss of appetite or diarrhea last more than two weeks, a medical evaluation is essential.
- Neurological Symptoms: Experiencing memory trouble, numbness, or tingling in hands and feet? These signs may suggest nerve involvement and should never be ignored.
- Recurring Mouth Ulcers or Swollen Tongue: These oral symptoms often indicate low folate and need proper diagnosis.

What is the Recovery Process After Folate Deficiency Treatment
Recovering from folate deficiency isn't just about taking a supplement-it's a step-by-step process that includes proper medical follow-up, healthy eating habits, and consistent lifestyle changes.
What to Expect After Starting Treatment
Most individuals begin to feel better within a week or two of starting folic acid supplementation. Fatigue, pale skin, and irritability may gradually fade. Red blood cell counts usually normalise within 6 to 8 weeks, depending on how severe the deficiency was.
Follow-Up and Monitoring
Regular check-ins help ensure your recovery stays on track:
- Initial follow-up: Within 4 weeks to check improvement in symptoms and lab values.
- Repeat blood tests: Complete blood count (CBC) and serum folate every 6-8 weeks.
- Long-term reviews: Once stabilized, twice-a-year checkups may be recommended, especially for those with chronic conditions or dietary restrictions.
Lifestyle and Diet Recommendations
A strong recovery includes more than just medication-it relies on long-term changes in diet and habits:
- Eat folate-rich foods: Include spinach, lentils, oranges, avocados, and fortified grains.
- Limit alcohol intake: Alcohol interferes with folate absorption and should be reduced or avoided.
- Maintain hydration and balanced meals: This supports digestion and nutrient absorption.
- Consider a multivitamin: Under a doctor's guidance, especially if you're at a continued risk of deficiency.
Long-Term Outlook
With early treatment and proper follow-up, most people recover fully from folate deficiency. However, the outlook depends on the underlying cause.
- If due to poor diet, long-term recovery is excellent with proper food habits.
- If caused by a chronic condition, ongoing medical management may be necessary.
- Pregnant women typically need folate supplements throughout pregnancy to prevent birth defects.

What Precautions Can Help Prevent Folate Deficiency?
Folate deficiency can often be avoided through simple lifestyle choices and timely health checkups. Taking preventive steps not only supports red blood cell production but also helps prevent complications like anemia and neurological problems.
Prevention Strategies
Lifestyle Modifications
- Eat a Folate-Rich Diet: Include leafy greens (spinach, kale), legumes, oranges, avocados, and fortified grains regularly.
- Limit Alcohol Consumption: Alcohol interferes with folate absorption and increases nutrient loss.
- Avoid Overcooking Vegetables: Excessive heat can destroy folate in foods. Opt for steaming or light cooking.
- Use Folate Supplements if Advised: Pregnant women, people with digestive disorders, or those on certain medications may need daily folic acid supplements.
Regular Screenings and Health Monitoring
- Routine Blood Tests: Especially important for individuals with chronic health issues, pregnancy, or dietary restrictions.
- Medication Reviews: Check with your doctor if any prescribed drugs might affect folate levels (e.g., anticonvulsants, methotrexate).
- Prenatal Checkups: Women planning pregnancy should take folic acid as recommended to prevent neural tube defects.
Potential Complications If Left Untreated
- Megaloblastic Anemia: A condition where red blood cells are abnormally large and underdeveloped.
- Neurological Issues: Including numbness, confusion, or memory loss.
- Pregnancy Complications: Increased risk of birth defects like spina bifida in unborn babies.
- Poor Immune Function: Folate is essential for cell division and immune health.
