Stress causes elevated cholesterol, as eMedicineHealth reports. Among other ways, stress often triggers an individual to eat fat-rich foods as a consolation, leading to elevated blood cholesterol. Stress also raises blood cholesterol by causing hormonal changes in the blood, which result from the body's response to stress, states Prevention.com.
Other than stress, other causes of elevated blood cholesterol include alcohol intake and increased body weight, according to eMedicineHealth. High blood cholesterol is also an inherited trait.
When the level of cholesterol in the blood increases, the condition predisposes an individual to diseases, says eMedicineHealth. Consequently, it is advisable for individuals age 20 years and older to undergo blood cholesterol testing at five-year intervals.
