Biological variations within a group can impact health and medical practices. East Indians have a variety of relatively common biological variations. This paper will discuss two of these variations: the existence of lactase deficiencies and an increased risk for heart disease.

The inability to properly digest lactose is common among those of East Indian descent. When dairy products are consumed, symptoms can include bloating or abdominal pain. According to a study published in the Journal of Gastroenterology and Hepatology, lactase deficiency is relatively common in populations with a strong East Indian heritage, with estimates ranging from 30% to 80% of individuals affected (Singh, S., & Arora, A., 2016).

Another common variation among populations of East Indian descent is coronary artery (CAD). The condition CAD occurs when plaque accumulates in arteries that deliver blood to the body’s heart. This leads to reduced blood flow. The risk of a cardiovascular problem or heart attack can be increased. A study published in the Indian Heart Journal found that South Asian populations, including those of East Indian descent, have a higher risk of CAD compared to other populations (Shah, P., & Chugh, S., 2014). The study found that South Asian populations, such as those of East Indian descent, have a higher risk of coronary artery disease (CAD) compared to other populations.

The two biological differences that are most common in East Indians populations include lactase deficiency, and increased coronary artery risk. This can impact health care practices. Healthcare providers should be informed of the biological differences to ensure culturally sensitive healthcare.
