When talking about essential vitamins and minerals, most people think of calcium, iron, or vitamin B. But zinc is one of the most critical minerals in the body – even if less discussed.
There are groups at high risk of zinc deficiency: People with eating disorders, digestive problems, chronic illnesses, as well as vegetarians and vegans – since most sources of zinc are found in animal-based foods.
So what are the clear signs that the body lacks zinc? Here are eight of them.
1. Wounds that are slow to heal
One of the common signs – especially among adults – is slow wound healing. Since zinc is essential for immune system function and the body’s ability to fight infections, a deficiency is expressed in delayed wound closure and a tendency to recurrent infections.
2. Hair loss
If hair becomes thin or falls out abnormally, it may be due to zinc deficiency. Studies link low levels of zinc with conditions of hair loss – temporary or chronic – including alopecia areata, stress-induced shedding, and even typical male pattern baldness.
3. Acne
Not every pimple comes from a mineral deficiency, but studies show that people suffering from acne tend to have lower zinc levels compared to others. Zinc treatment may sometimes reduce outbreaks and help restore the skin.
4. Chronic diseases
Zinc plays a central role in reducing inflammation and free radical damage. A lack of it increases the risk of chronic illnesses such as pneumonia or diabetes. In addition, the body struggles to fight infections, which increases vulnerability to disease.
5. Decline in vision
The eyes – especially the retina – contain large amounts of zinc. With age, zinc levels naturally decrease, and this has been linked to the development of age-related macular degeneration (AMD) – one of the most common causes of blindness. The good news: Zinc supplements may slow the process, but a doctor should be consulted before taking them, since excess zinc is also dangerous.
6. Loss of taste and smell
Zinc is directly involved in our basic senses. A deficiency may impair the ability to taste and smell, and sometimes even cause a complete loss of both senses. Studies have shown a connection between low zinc levels and this impairment, especially among older adults.
7. Hearing decline
In some cases, zinc deficiency is linked to hearing problems – including tinnitus (ringing in the ears) and even actual hearing loss. A connection was found between the severity of the condition and zinc levels in the blood: The greater the deficiency, the more severe the symptoms may be.
8. Stunted growth
Among infants, children, and adolescents – zinc is especially essential for growth and development. A deficiency may lead to delayed growth and puberty, and sometimes to secondary problems such as loss of appetite and recurrent diarrhea, which further increase the deficiency.
Zinc deficiency: How can it be diagnosed and treated?
Diagnosis is usually done through blood tests and examining clinical symptoms. In mild deficiency cases, it is sometimes possible to make up for it through diet:
Foods rich in zinc include beef, chicken, fish, eggs, nuts, legumes, and whole grains.
Vegetarians and vegans can focus on legumes, seeds, and nuts – but may sometimes need supplements as recommended by a doctor.
It is important to remember: Excess zinc is no less dangerous than deficiency. Excessive intake may cause nausea, diarrhea, liver damage, and even harm to the immune system.
In conclusion, zinc may not get the spotlight like calcium or iron, but it is essential for almost every system in the body. A deficiency can manifest in hair, skin, vision, hearing, and the immune system. Paying attention to early signs, maintaining proper nutrition, and, if necessary, taking supplements under medical guidance – can ensure the body receives this vital mineral and prevent serious health consequences.
