Multifactorial Essay

Multifactorial or complex inheritance health conditions have a genetic component in origin and tend to run in the family depending on how close one is with the affected family member. They are caused by mutation in single genes and multiple contributing factors that cause these conditions. Such contributing factors include lifestyle, nutrition, alcohol use and smoking, pollution and certain medicines. The health conditions include heart diseases, diabetes, Alzheimer disease, birth defects such as cleft palate, cancers of the breast, arthritis and multiple sclerosis. The complex health conditions are difficult to treat and study because the precise causative factors have a multiple origin hence difficult to identify.
Question #1- Factors that can be associated with complex inheritance disorder
Multifactorial inheritance disorders arise as a result of a number of multiple contributing factors may not be genetic in origin. Nutrition and diet
High cholesterol foods and food with high fat contents result in heart conditions as a result of deposition of the cholesterol and plaques in arteries causing their hardening and blockage of small arteries hence arteriosclerosis. This results in their necrosis hence heart attacks, myocardial infarction and stroke. Additionally, obesity and diabetes are caused by unhealthy eating and poor balanced diet (Gelb, & Chung, 2014). High calorie intake by individuals increases the propensity of developing certain cancers and cardiovascular conditions which are classifies as multifactorial health disorders. Diet defines every persons growth, development and general health therefore uncontrolled diet such as eating high salty foods, result in elevated blood pressure that cause complex disorders. Obesity and high sugar intake through diet causes diabetes, a complex inheritance
