Zinc is a crucial mineral that our body needs for performing various functions like immune function, wound healing, and DNA synthesis. While zinc deficiency is a concern for many, consuming more zinc than needed can pose harmful to our bodies.
To understand the signs of excess zinc in our body, OnlyMyHealth team interacted with Dr Roohi Pirzada, Senior Physician and Critical Care Specialist, Mumbai.
Explaining the importance of zinc in our body, Dr Pirzada said, “Zinc helps in boosting the immune system to fight off invading viruses and bacteria. Zinc is also used to make genetic material i.e DNA and proteins. Zinc is also needed in growth phases like adolescence, pregnancy and childhood. Lack of zinc leads to loss of hair, eye soreness, lack of appetite and can affect sexual function in men.”
But then excess zinc can harm your health and may lead to unpleasant consequences. Here are some signs listed with the help of Dr Pirzada that say you have excess zinc in your body.
1. Gastrointestinal Issues
One of the most common signs of excess zinc is gastrointestinal problems. “These can include nausea, vomiting, diarrhoea, and abdominal cramps,” Dr Pirzada said. These symptoms typically occur when zinc intake exceeds the body's ability to absorb and excrete it, leading to irritation of the gastrointestinal tract. According to a study published by the National Institute of Health, zinc can cause intestinal hyperpermeability, leaky gut, which itself can be secondary to increased nitric oxide and oxidative stress, thereby leading to diarrhoea.
2. Reduced Immune Function
While zinc is known for its role in supporting the immune system, excess zinc can actually have the opposite effect. Too much zinc can suppress immune function, making you more susceptible to infections and illnesses.

3. Lowered HDL Cholesterol
High-density lipoprotein (HDL) cholesterol is often referred to as "good" cholesterol because it helps remove other forms of cholesterol from your bloodstream. However, Dr Pirzada said that excess zinc can lower HDL cholesterol levels, which may increase the risk of heart disease.
4. Impaired Wound Healing
As per a published study, zinc plays a crucial role in wound healing, but too much zinc can actually impair this process. Excess zinc can interfere with the body's inflammatory response, which is essential for healing, leading to delayed wound healing and potential infections.

Dr Pirzada said that excess zinc can also lead to lethargy, fatigue, nausea, vomiting, sweating and weakness. “In serious cases chelators, which are medicines to remove zinc from the blood stream may be needed. These medications bind to excess zinc and excrete the same through urine.”
Adding further, she said, “Certain diuretics like hydrochlorothiazides and chlorthalidone can lower the zinc level in the blood stream. In mild cases milk intake helps as calcium and phosphorus in milk bind with excess zinc.”
Conclusion
While zinc is an essential mineral for good health, it's important to consume it in moderation. Excess zinc can lead to a range of health issues, from gastrointestinal problems to neurological symptoms and even organ damage. If you suspect you may have excess zinc in your body, it's important to consult with a healthcare professional for proper evaluation and guidance.
