Causes of High Cholesterol

Chronic stress can lead to various health issues, including elevated cholesterol levels. Research indicates that it increases the risk of high LDL ("bad") cholesterol and reduces levels of HDL ("good") cholesterol. Stress hormones like cortisol and adrenaline trigger changes that may result in higher blood sugar and inflammation. Over time, this can lead to increased production of cholesterol and triglycerides by the liver. Managing stress is crucial for maintaining overall cardiovascular health.

Unfiltered Coffee

That French press, Turkish coffee, or espresso habit may brew up trouble for your cholesterol. These coffees don’t use a filter, so oily compounds in the beans called diterpenes seep into your cup. These oils can raise LDL cholesterol. While a serving or two a day is OK, experts recommend no more than four unfiltered coffees a day.

Certain medications, including specific birth control pills, retinoids, corticosteroids, antivirals, and anticonvulsants, can have unexpected effects on your cholesterol levels. Some medications for high blood pressure, like diuretics and older forms of beta-blockers, may also contribute to elevated cholesterol. It's essential to discuss your medications with your doctor, as you might require a different dosage or an alternative medication to manage cholesterol effectively. Regular communication with your healthcare provider is crucial for addressing any potential medication-related impact on cholesterol.

Thyroid hormones play a role in regulating cholesterol levels by aiding in the removal of excess cholesterol. When you have an underactive thyroid, known as hypothyroidism, your total and LDL cholesterol levels may increase. If you experience symptoms like fatigue, dry skin, muscle weakness, or aches, it's crucial to discuss them with your doctor. A blood test can help screen for hypothyroidism, allowing for appropriate management and addressing potential impacts on cholesterol.

Type 2 diabetes can lead to elevated blood sugar levels, causing sugar to attach to proteins, including cholesterol molecules. This modification makes cholesterol more harmful. Individuals with type 2 diabetes often have more small, dense LDL particles, increasing the risk of heart disease. Additionally, they may have lower levels of protective HDL cholesterol, which may not function as effectively in removing the "bad" cholesterol. Managing blood sugar levels is crucial for overall cardiovascular health in individuals with type 2 diabetes.

The decline in the sex hormone estrogen during menopause influences cholesterol levels, leading to an increase. Research indicates that LDL and total cholesterol levels tend to rise around and after the final menstrual period. Compounding this, women often gain an average of 8 to 10 pounds after menopause and may reduce their physical activity, further contributing to an increased risk of high cholesterol. Managing weight and maintaining regular exercise can be beneficial for addressing cholesterol changes associated with menopause.

Prolonged sitting, whether at a desk or on a couch, is associated with various health risks, including obesity, heart disease, and high cholesterol. Extended periods of sitting lead to a significant drop (95%) in an enzyme that converts harmful LDL cholesterol into beneficial HDL cholesterol. To protect your heart health, it's crucial to take frequent breaks. Stand up at least every 30 minutes, and if possible, incorporate a 5-minute walk every hour to counteract the negative effects of prolonged sitting.

The liver plays a crucial role in cholesterol regulation, producing, processing, and breaking down cholesterol. When the liver functions improperly, it can impact cholesterol levels. Nonalcoholic fatty liver disease (NAFLD) is a prevalent condition, affecting nearly 1 in 4 adults, where excess fat accumulates in the liver. A more severe form, known as NASH (nonalcoholic steatohepatitis), causes inflammation and scarring of the liver, potentially leading to liver cirrhosis. Addressing liver health is essential for maintaining optimal cholesterol levels and overall well-being.

Excessive alcohol consumption can impact your cholesterol levels, as the liver, responsible for processing cholesterol, also breaks down alcohol. A study revealed that men who engaged in heavy drinking, roughly 4½ drinks or more at once, had poorer cholesterol levels compared to non-heavy drinkers. This effect was observed even among those who occasionally binge drank. To maintain healthy cholesterol levels, it's advised to consume alcohol in moderation — no more than one drink a day for women and two for men.

During pregnancy, the body utilizes cholesterol to support the growth and development of the fetus, causing cholesterol levels to increase by up to 50% in the second and third trimesters. These elevated levels can persist for approximately a month after childbirth. While this temporary spike typically doesn't pose harm to the mother or baby, individuals with pre-existing high cholesterol should have their levels monitored closely by a healthcare professional during and after pregnancy.

Cholesterol can impact kidney function, with research indicating that high cholesterol levels may harm the kidneys and elevate the risk of kidney disease. Conversely, kidney problems can influence cholesterol levels. Studies show that nephrotic syndrome, a kidney disorder, can lead to increased LDL and total cholesterol levels. Additionally, chronic kidney disease is associated with lower HDL levels. Monitoring both cholesterol and kidney health is essential for comprehensive well-being.

While saturated fat is commonly implicated in heart disease, excessive sugar intake is also a contributor. A diet rich in sugar prompts the liver to produce more LDL cholesterol and triglycerides while decreasing HDL cholesterol. Research indicates that individuals obtaining 10% or more of their calories from added sugars were up to three times more likely to have low HDL levels compared to those consuming less than half that amount. Monitoring and moderating sugar intake are crucial aspects of a heart-healthy diet.
