Why Does Being Overweight Cause High Blood Pressure?

Obesity is a condition that can have many health complications, including high blood pressure. Even being overweight, but not obese, can affect blood pressure in a unfavorable way. Hypertension, or chronic high blood pressure, is one of many conditions that can decrease life expectancy in adults.
Overweight individuals may have a higher blood volume and an increased production of insulin. Blood pressure is also increased by raised sodium levels and thickening of the arteries. High blood pressure may additionally be caused by a sedentary lifestyle, high intake of alcohol and vitamin deficiencies.
Obesity alone can put one at a higher risk of heart attack and of stroke. Being overweight and having high blood pressure also increases the likelihood of diabetes and other medical conditions.
High blood pressure may not cause any symptoms. However, symptoms that are common in people with high blood pressure include blurred vision, nausea and headaches.
If you have been identified as being overweight based on height, weight and BMI, it is a good idea to get your blood pressure checked by a health care professional.
Becoming overweight can be prevented through a healthy diet and moderate exercise. High blood pressure can be prevented by maintaining a healthy weight, not smoking or drinking, and exercising regularly. If you are overweight, losing weight can greatly reduce high blood pressure or even resolve the condition.
