There are several factors that can cause a sudden increase in cholesterol levels. These include:

• Stress: High stress levels can cause a sudden spike in cholesterol. When a person experiences stress, their cortisol levels rise, which can trigger the release of extra cholesterol.

• Diet: Eating too much saturated fat or trans fats can result in unhealthy cholesterol levels. A high-sugar diet can also cause a sudden increase in cholesterol.

• Medications: Some medications, such as oral anabolic steroids, antihypertensives, thiazide, beta-blockers, retinoids, and cyclosporine, can cause elevated cholesterol levels as a side effect.

• Lifestyle habits: Smoking and drinking alcohol can raise your total cholesterol. Physical inactivity can also contribute to high cholesterol levels.

• Pregnancy: During pregnancy, hormonal and metabolic processes can cause a temporary spike in cholesterol levels.

• Coffee: Drinking excessive amounts of coffee can result in a cholesterol spike due to the presence of diterpenes, chemical compounds that may raise cholesterol.

Its important to note that high cholesterol can also be caused by underlying health conditions such as thyroid disease, kidney disease, and diabetes. If you experience a sudden increase in cholesterol levels, its important to talk to your doctor to determine the underlying cause and develop a treatment plan.
