Over weight adults have high blood pressure than normal weight people. With high blood pressure and obesity, cardiovascular risk increases by increasing LDL cholesterol. According to the research, obesity increased cardiac output and blood volume and arterial resistance.
Obesity leads to high secretion of insulin in trying to reduce the concentration of excess sugar in blood. The secretion of this insulin is high compared to non-obese people. The insulin secreted by pancreas is responsible for many modifications in your body [Gastric bypass surgery to reduce obesity].
The secreted insulin leads to thickening of vessels which is responsible for increase in rigidity, thus increasing your hypertension. Because of the increase in secretion of adrenalin, cardiac output is increased.
The insulin leads to water and salt re-absorption by the kidney, which increases the volume of blood and thus leads to hypertension. Obesity or over weight is responsible for an over sensitiveness to sodium, which increases the peripheral arteries rigidity.
Treatment of obese adult with hypertension:
Treatment of over weight adult with high blood pressure requires physiological changes related to obesity hypertension. Lifestyle changes, which include weight reduction and increased physical activity can directly influence blood pressure levels and improve high blood pressure in obese and hypertensive adults.
Light cardiovascular activities like swimming, walking, biking and yoga can help in controlling blood pressure. Maintain a normal weight with these cardio exercises. Exercising for 30 minutes regularly, five times a week is suggested. Limit the amount of sodium content in your diet.
Limit the amount of caffeinated and alcoholic beverages. Reduce stress and stop smoking. Decrease bad cholesterol levels in your diet and increase good cholesterol levels. Simple measures like using stairs instead of elevator can eventually burn calories and help to reduce weight.
