Zinc is an essential nutrient found in both plant and animal sources, playing a vital role in maintaining skin health, strengthening the immune system, supporting cell growth, and managing inflammation. A deficiency in zinc can lead to a range of health issues affecting various bodily functions. What are the signs to look out for? Find out more below.
Causes of Zinc Deficiency
Zinc is crucial for several body functions. Some primary benefits include:
- Activating over 300 enzymes necessary for metabolism, digestion, nerve function, and numerous other processes
- Enhancing the immune system
- Promoting wound healing
- Supporting the development and function of immune cells
- Encouraging healthy skin, DNA synthesis, protein production, and reducing acne
The most common cause of zinc deficiency is a lack of foods rich in zinc. Certain medical conditions, like celiac disease, chronic kidney or liver disease, diabetes, and chronic diarrhea, can also contribute to zinc deficiency.
Symptoms of Zinc Deficiency
The daily requirement for zinc is typically around 8-11 mg. Although the body doesn’t need large amounts, a deficiency can still develop.
Symptoms of zinc deficiency often overlap with other nutritional deficiencies, but specific symptoms relate to zinc’s roles in the body. Common signs of zinc deficiency include:
Skin and Hair
- Rashes (particularly around the mouth)
- Delayed wound healing
- Skin ulcers
- Hair loss
- Acne
Immune and Respiratory Issues
- Slow healing from injuries
- Frequent colds
- Worsening asthma symptoms
Digestive System
- Diarrhea
- Unintended weight loss
Sensory Effects
- Reduced sense of smell and taste
- Vision problems in older adults
Cognitive Symptoms
- Difficulty with concentration
- Feelings of depression
Sexual Health
- Sexual dysfunction
Growth Impairment
Toddlers are at an increased risk of growth delays due to zinc deficiency. Zinc-deficient children may have decreased appetites, resulting in below-average weight and lack of other nutrients crucial for growth.
Treatment for Zinc Deficiency
To address zinc deficiency, it’s essential to meet daily zinc requirements through diet or supplements.
Consuming Zinc-Rich Foods
If diagnosed with a zinc deficiency, dietary adjustments can help. Foods high in zinc include:
- Red meat
- Zinc-fortified cereals
- Yogurt
- Chickpeas
- Oatmeal
- Milk
- Oysters
- Poultry
Vegetarians can obtain zinc from nuts, such as cashews, peas, and almonds.
Supplements
Zinc supplements are another way to meet daily requirements. However, consult a doctor regarding the appropriate dosage, as zinc supplements may interact with certain medications like antibiotics, arthritis treatments, and diuretics.
Zinc deficiency can arise due to inadequate dietary intake or underlying conditions. If you experience symptoms, consult a doctor or try the Ai Care consultation feature, available on the App Store or Play Store.
