What Are Nutritional Disorders?

Nutrition disorders occur when your body does not get enough, too much, or the wrong types of nutrients from food. Nutrients fuel your body, and imbalances prevent proper growth, development, and bodily functions. Common issues include insufficient food intake, long-term nutrient deficits (vitamins, proteins, minerals), and overnutrition.

• Mental Struggles: Stress, anxiety, depression may cause poor eating habits.
• Genetic Conditions: Disorders such as sickle cell anemia, PKU, or cystic fibrosis affect nutrient processing.
• Chronic Diseases: Cancer, Crohn’s disease, and kidney disease can impair absorption and nutrient use.

Symptoms Of A Nutritional Disorder

• Fatigue, dry/frizzy hair, pale skin, swelling, depression, trouble focusing
• Hair loss, weight loss, food obsession, growth delays, irritability
• Muscle wasting, mouth sores, slow healing, rashes, anorexia, infections, dry skin

How Are Nutritional Disorders Treated?

Treatment varies with cause and severity. Many improve with nutritional changes or supplementation (e.g., increasing iron-rich foods for anemia). Severe cases might require medication or tube feeding, but dietary improvements are foundational.

How Can I Prevent Nutritional Disorders?

According to Dr. Thomas A. Borland, diversity in diet is critical—consume leafy greens, colorful fruits and vegetables, nuts, seeds, beans, whole grains, fatty fish, egg yolks, and low-fat dairy. Supplements may be needed for pregnant women or those with malabsorption. Consult professionals for personalized advice.
