Vitamins play a vital role in maintaining overall health and well-being. They are essential micronutrients that the body requires in specific quantities to function optimally. However, vitamin deficiency is a prevalent issue among adults that can lead to various health issues. Now, you will explore the 15 most common causes of adult vitamin deficiency before starting any new dietary regimen. It’s a good idea to consider getting a vitamin profile test to assess your nutritional needs.
- Poor Diet
One of the primary causes of vitamin deficiency is an inadequate diet. A diet lacking in various fruits, vegetables, whole grains, and lean proteins can lead to a deficiency in several vitamins, including vitamins A, C, D, and E.
- Insufficient Sun Exposure
Vitamin D deficiency is widespread among adults who do not get enough sun exposure. The skin produces vitamin D when exposed to sunlight, so limited outdoor activity or strict sun protection measures can result in a deficiency.
- Gastrointestinal Disorders
Certain gastrointestinal disorders, such as celiac disease, Crohn’s disease, and irritable bowel syndrome (IBS), can interfere with nutrient absorption, leading to vitamin deficiencies.
- Alcohol Abuse
Excessive alcohol consumption can disrupt the absorption of vitamins, particularly B vitamins, in the digestive system. Chronic alcoholism is often associated with vitamin B1 (thiamine) deficiency.
As people age, the body becomes less efficient at absorbing and utilising vitamins. This can result in deficiencies, especially of vitamins B12, D, and calcium.
- Pregnancy and Breastfeeding
Pregnant and breastfeeding women have increased nutrient requirements. If their diets do not meet these demands, they may develop deficiencies in vitamins like folate, vitamin D, and iron.
Certain medications, such as antacids, proton pump inhibitors, and antibiotics, can interfere with nutrient absorption and contribute to vitamin deficiencies like B12, calcium, and magnesium.
- Vegetarian and Vegan Diets
Vegetarian and vegan diets may lack essential vitamins like B12, primarily found in animal-based foods. Vegans, in particular, should be cautious about their B12 intake.
- Food Allergies and Sensitivities
Individuals with food allergies or sensitivities may eliminate entire food groups from their diets, potentially leading to specific vitamin and mineral deficiencies.
Smoking damages the lungs and can reduce vitamin C absorption, which is essential for a healthy immune system and skin.
- Chronic Illnesses
Chronic illnesses, such as diabetes and kidney disease, can impact the body’s ability to regulate and metabolise certain vitamins and minerals, including vitamin D and potassium.
- Inflammatory Bowel Diseases
Inflammatory bowel diseases like Crohn’s and ulcerative colitis can damage the intestinal lining, hindering nutrient absorption. Vitamin D and vitamin B12 deficiencies are common in these conditions.
- Malabsorption Disorders
Conditions like cystic fibrosis and chronic pancreatitis can interfere with the absorption of fat-soluble vitamins (A, D, E, and K) and fat-absorbing vitamins (K).
- Weight Loss Surgery
Certain weight loss surgeries, such as gastric bypass and gastric sleeve procedures, can reduce the body’s ability to absorb nutrients, potentially leading to vitamin deficiencies like B12, iron, and calcium.
- Stress and Poor Lifestyle Habits
High-stress levels, combined with poor lifestyle habits like lack of sleep and inadequate physical activity, can deplete vitamins and increase the risk of deficiency.
A vitamin blood test typically checks for deficiencies in vitamins A, B1 (thiamine), B2 (riboflavin), B3 (niacin), B6 (pyridoxine), B9 (folate), B12 (cobalamin), C (ascorbic acid), D (cholecalciferol), E (tocopherol), and K (phylloquinone). It can also assess your levels of essential minerals like calcium, magnesium, and iron.
Regular blood test monitoring or a vitamin profile test is essential for maintaining good health and preventing deficiency-related health issues. If you suspect a vitamin deficiency or are at risk due to the above causes, consult your healthcare provider for a vitamin blood test. They can recommend the appropriate test and vitamin test package and guide you in making dietary and lifestyle changes to address deficiencies.
