  6. Who remains at highest risk of zinc deficiency?

    • Nutritional deficiency is a rare reason; however, it is considered as one of the important reasons behind zinc deficiency leading to multiple health disorders in developing countries
    • Extreme alcoholism accelerates zinc excretion from the body and thus the body is left with low zinc content
    • Gastrointestinal issues related to improper absorption of zinc by the body
    • Severe and prolonged liver disorders
    • Diabetes
    • People who stick to vegetarian diet; however, don't meet zinc requirements
    • Pregnant women remain at high risk of zinc disorders
    • Kidney diseases
    • Crohn's disease and Sickle Cell disease lead to sudden drop of Zinc in body

  7. Can you ever have excess Zinc in body?

    If your body has more than 225 mg of zinc, then you are said to suffer from Zinc toxicity. Zinc overdose through diet is a rare condition. However, taking prolonged supplements can lead to excess zinc or what is known as zinc toxicity in body. Living in industrial areas producing excess zinc is also a primary causative reason behind abundant zinc in body.

  8. How will you know if you have excess Zinc in body?

    Following are few of the symptoms that show zinc overdose:

    • Severe and uncontrolled vomiting
    • Stomach pain and diarrhea
    • Nausea
    • Headaches
    • Fever
    • Zinc chills are associated with exposure to industrial zinc
    • Excess Zinc also disturbs iron balance leading to anemia
    • Zinc overdose leads to lowering of good HDL in body
    • Zinc in abundance reduces white blood cells in body
    • If you are taking any antibiotics, your body stops responding to the medication if your are suffering from zinc overdose
  9. Zinc contributes at preventing Diabetes. Is it really true?

    Yes. Healthy levels of zinc can help you to prevent Diabetes to a great extent. Following are the three vital roles played by zinc with respect to insulin:

    • Zinc is abundantly present in the pancreas where insulin is produced. Here, it enhances cell development and overall health of cell
    • Zinc binds itself to insulin receptors and thus ensures insulin storage and secretion when glucose enters the blood
    • Zinc is important for good insulin sensitivity

  10. What do you mean by insulin sensitivity?

    Insulin is produced by pancreas when there is excess sugar in blood. Following which, the cells absorb glucose content and thus, the blood is left with normal sugar levels. And the person does not suffer from diabetes.

    Insulin sensitivity may be termed as a relation between amount of insulin required to help cells absorb required levels of glucose. A good insulin sensitivity suggests that a small amount of insulin is required by the body. On the other hand, when the body requires large insulin for small glucose content, the body is said to be insulin resistant.

  11. Why does lack of zinc lead to hair loss?

    As already mentioned in Q.1, Zinc is vital for protein synthesis, vitamin and mineral absorption. When the body lacks zinc, above functions cannot take place efficiently and thus lead to thinning hair as one of the many disorders.

    Not only lack of zinc, but an excess of zinc can lead to the similar problem too. Zinc overdose may have hormonal imbalance including high testosterone level. This condition again promotes loss of hair.

  12. What are the diagnostic tests available for Zinc disorders determination?

    Following are some of the laboratory tests helpful for Zinc deficiency determination:

    • Serum tests for Zinc deficiency
    • Urine test also helps in determining Zinc content in body
    • Plasma Zinc test
    • A simple taste test is also conducted
    • Hair test as Zinc deposits in hair strands. Studying zinc content in hair gives an overall idea of zinc in body.
  13. How is Zinc related to thyroid disorders?

    Thyroid gland functions are regulated by TSH (Thyroid Stimulating Hormone) produced by pituitary gland. Healthy TSH levels guarantee adequate T3 and T4 levels in body. Production of this TSH depends upon proteins, Vitamin B-12, Magnesium and the very important Zinc. Therefore, any form of zinc disorders result in impaired thyroid functions.

  14. Zinc regulates your heart beat. How?

    Calcium balance in heart cells is important to regulate healthy heart beat patterns. A heart, deficient in calcium, leads to fatal arrhythmias (irregular heartbeat pattern); making patients susceptible to heart failures. Calcium movement in heart cells is regulated by zinc. Therefore, if your are deficient in zinc, your body develops calcium imbalance leading to related heart disorders.

    Further, zinc deficiency may also lead to lack of cardio-protective substance and triggers inflammatory conditions; thus risking cardiovascular threats.
