High blood lipid levels:
Obesity most commonly causes an increase in blood triglyceride levels
In some patients, blood cholesterol levels may also increase, mainly manifesting as type IV hyperlipoproteinemia, followed by type IIb hyperlipoproteinemia.
The fat metabolism characteristics of obese individuals include increased plasma free fatty acids, elevated blood lipid components such as cholesterol and triglycerides, indicating fatty acid metabolism disorders. Plasma cholesterol levels in obese individuals can reach 5.2 mmol/L or higher in 55.8% of cases. In men after 60 years old and women after 50 years old, plasma cholesterol levels significantly increase.
When suffering from obesity, the body’s utilization of free fatty acids decreases, leading to accumulation of free fatty acids in the blood and increased blood lipid capacity.
Patients with hypertriglyceridemia caused by carbohydrates are prone to obesity
When these patients consume more or normal amounts of carbohydrates, plasma triglycerides increase; reducing carbohydrate intake can improve or even eliminate high triglycerides. Similarly, weight loss can also decrease plasma triglycerides to normal levels. The increase in plasma cholesterol and triglycerides is proportional to the degree of obesity. Therefore, it is crucial for obese individuals to control their diet and lose weight.
