You’ve probably heard that high cholesterol isn’t good. Actually your body needs cholesterol to function correctly for cell membranes, hormones, and vitamin D. But when your cholesterol stays unhealthy too long, you’re at high risk of having serious health problems.

👉 There are many causes of high cholesterol. For some people, genetic conditions such as familial hypercholesterolemia cause high cholesterol no matter how healthy their diet, exercise habits, or other lifestyle choices are.

There are some medical conditions that can also affect your cholesterol levels:  
👉 An unhealthy diet with high levels of saturated fat (red meat, cream and other full-fat dairy products, butter, cheese, cookies, cakes, and other baked goods)  
👉 Fried foods  
👉 Smoking  
👉 Diabetes  
👉 Obesity  
👉 Alcohol use  
👉 Lack of exercise  
👉 Age  
👉 High blood pressure  
👉 Family history of stroke or heart disease  
👉 Chronic kidney disease  
👉 HIV/AIDS  
👉 Hypothyroidism  
👉 Lupus  
👉 Birth control pills  

Possible symptoms of high cholesterol:  
👉 High blood pressure

👉 Peripheral artery disease (PAD)  
👉 Coronary heart disease

✅ Be sure you’re seeing your doctor for regular checkups. If your cholesterol is increasing too much, you may have to control it with lifestyle changes. Your doctor might suggest you:  
👉 Drop extra pounds  
👉 Get more exercise  
👉 Stop smoking and using alcohol products  
👉 Lower the stress in your life  
👉 Lower your cholesterol by eating healthily (less salt, reduce animal fats in your diet, more unsaturated fats, fruits, vegetables, and whole grains)

If lifestyle changes don’t lower your numbers enough, your doctor may recommend you take cholesterol-lowering medications:  
👉 Statin drugs  
👉 Hormone replacement therapy for menopause  
👉 Other medications to lower LDL cholesterol and triglycerides  


Good vs bad cholesterol: though high cholesterol isn’t good, your body needs cholesterol to function correctly for cell membranes, hormones, and vitamin D.

Good vs Bad Cholesterol

Proteins carry cholesterol through your blood. This combination of protein and cholesterol is called lipoprotein. There are two different types of lipoprotein:

👉 HDL (high density lipoprotein) takes cholesterol from cells to your liver, which breaks it down as a waste product so your body can get rid of it. Doctors often call HDL the “good” cholesterol, high levels of HDL mean you have less risk of heart disease. But too high HDL cholesterol levels don’t protect you any more, they might be harmful.  
👉 LDL (low density lipoprotein) brings cholesterol to your cells so they can use it. When you have too much cholesterol, it builds up in your cells and can lead to disease. High levels of LDL (the “bad” cholesterol) mean you have excess cholesterol in your body.  
👉 When these numbers are off and total cholesterol gets too high, your chances of health problems go up.

Unhealthy cholesterol level is silent, you could have too many lipids in your blood and not know it for many years. Your doctor uses a simple blood test as the only way to find out. For healthy cholesterol levels, your test result should be:

✅ HDL: more than 50 mg/dL  
✅ LDL: 70 - 130 mg/dL  
✅ Total cholesterol: less than 200 mg/dL  


Learn what your cholesterol test results mean and what a healthy cholesterol level is. Discover what your cholesterol should be, and find out how to lower your cholesterol levels naturally.

It is especially important for modulating surgical stress and supporting recovery. When a patient undergoes surgery, the process induces stress on the body that results in the breakdown of muscle, affecting the body’s ability to heal and recover.

Sample menu of day before surgery: salmon, baked potato, steamed broccoli, green salad, glass of milk. Up until 3 hours before your surgery, avoid heavy meal with a large amount of fat.

## 🌿 CLEAR LIQUID 🌿

It is important that your body needs to get well hydrated before surgery, drink plenty of clear liquids such as water, plain tea, clear broth, Gatorade, soda, apple juice, or Boost Breeze liquid supplement. If you have diabetes, avoid juice, milk or creamer, regular soda, and sports drinks, since these can raise your blood sugar levels.

Notice: starting 2 hours before you arrive at the hospital, do not eat or drink anything, unless your doctor or nurse has told you otherwise.
