Cholesterol is a waxy substance found in all the cells of the body. It is a type of fat that is produced by the liver. Cholesterol also comes from animal-derived foods, such as meat and dairy products. It is an essential substance needed by the body for various purposes. Too much cholesterol, however, harms the body and increases the risk of various medical conditions, such as high blood pressure and heart diseases.
Different types of cholesterol exist in the body. Their normal values (measured in milligrams per deciliter or mg/dL) vary according to a person’s age and gender. Important cholesterol values include measuring the total cholesterol, non-HDL (non-high-density lipoprotein) cholesterol, HDL (high-density lipoprotein) cholesterol, and LDL (low-density lipoprotein) cholesterol.
Based on age and gender, the healthy cholesterol levels are:
| Total Cholesterol | Less than 170 mg/dL |
| Non-HDL | Less than 120 mg/dL |
| LDL | Less than 100 mg/dL |
| HDL | More than 45 mg/dL |
| Total Cholesterol | 125 to 200 mg/dL |
| Non-HDL | Less than 130 mg/dL |
| LDL | Less than 100 mg/dL |
| HDL | 40 mg/dL or higher |
| Total Cholesterol | 125 to 200 mg/dL |
| Non-HDL | Less than 130 mg/dL |
| LDL | Less than 100 mg/dL |
| HDL | 50 mg/dL or higher |
The test used to measure cholesterol levels is called a lipoprotein panel. The lipoprotein panel also gives the value for triglycerides (TGs). Triglycerides are not a type of cholesterol, but they are as important as most of the fat in the body exists as TGs. A high triglyceride level can increase the risk of diseases, such as high blood pressure, heart diseases, and pancreatitis. Triglycerides are also measured in the same units as cholesterol (milligrams per deciliter or mg/dL). The values or numbers for TGs are classified as:
- Normal: A triglyceride level of less than 150 mg/dL.
- Borderline high: A triglyceride level between 150-199 mg/dL.
- High: A triglyceride level between 200-499 mg/dL.
- Very high: A triglyceride level of 500 mg/dL or higher.
What is bad cholesterol?
Cholesterol (a type of fat or lipid) moves in the body combined with proteins. This combination of cholesterol and proteins is called lipoproteins. The low-density lipoprotein or LDL cholesterol is called bad cholesterol. High levels of this cholesterol increase risk for heart diseases and stroke.
When you have high levels of LDL cholesterol in the body, the LDL cholesterol can accumulate on the walls of the blood vessels forming a ‘plaque.’ The continuous cholesterol build-up or a plaque narrows the inside of the blood vessels with time. The narrowed blood vessel hampers the blood supply to the concerned organ. Thus, when the plaque is present in the heart, it can cause angina (chest pain) or a heart attack. Plaque build-up in the brain can cause a stroke.
Another type of cholesterol is HDL (high-density lipoprotein) cholesterol. It is also called “good” cholesterol as it absorbs cholesterol and carries it back to the liver. The liver then removes the cholesterol from the body. HDL cholesterol, thus, can lower your risk for heart diseases and stroke.
How often should I get my cholesterol levels checked?
The frequency of getting your cholesterol levels tested depends on your age, presence of risk factors, and family history like a history of heart diseases, stroke, diabetes, or high cholesterol.
The following provides general recommendations for various age groups.
People who are 19 years of age or younger should:
- Get the first test done between ages 9 to 11 years
- Repeat the test every 5 years
- For children, who have a family history of high blood cholesterol, heart attack, or stroke, the testing may start at 2 years of age
People who are age 20 years or older:
- Those between the age of 20 to 44 years should get tested every 5 years
- Women in the age group 45 to 54 years should get tested every 5 years
- Men in the age group 45 to 65 years should get their cholesterol levels checked every 1-2 years
- Women in the age group 55 to 65 years should get tested every 1-2 years

Ezallor (rosuvastatin)
Ezallor Sprinkle (rosuvastatin) is a prescription medicine used in adults along with diet to lower the level of your “bad” cholesterol (LDL) and lower the level of fat in your blood (triglycerides). This treats a variety of cardiovascular problems and reduces the risk of heart attack and stroke.FloLipid (simvastatin)
FloLipid Oral Suspension is a lipid-lowering agent that is derived synthetically from a fermentation product of Aspergillus terreus. FloLipid is used to reduce elevated total cholesterol (total-C), low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (Apo B), and triglycerides (TG), and to increase high-density lipoprotein cholesterol (HDL-C).
High Blood Pressure (Hypertension)
High blood pressure (hypertension) is a disease in which pressure within the arteries of the body is elevated. About 75 million people in the US have hypertension (1 in 3 adults), and only half of them are able to manage it. Many people do not know that they have high blood pressure because it often has no has no warning signs or symptoms.
Systolic and diastolic are the two readings in which blood pressure is measured. The American College of Cardiology released new guidelines for high blood pressure in 2017. The guidelines now state that blood normal blood pressure is 120/80 mmHg. If either one of those numbers is higher, you have high blood pressure.
The American Academy of Cardiology defines high blood pressure slightly differently. The AAC considers 130/80 mm Hg. or greater (either number) stage 1 hypertension. Stage 2 hypertension is considered 140/90 mm Hg. or greater.
If you have high blood pressure you are at risk of developing life threatening diseases like stroke and heart attack.

Low Blood Pressure (Hypotension)
Low blood pressure, also referred to as hypotension, is blood pressure that is so low that it causes symptoms or signs due to the low flow of blood through the arteries and veins. Some of the symptoms of low blood pressure include light-headedness, dizziness, and fainting if not enough blood is getting to the brain. Diseases and medications can also cause low blood pressure. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidneys; the organs do not function normally and may be permanently damaged.
Low Blood Pressure (Hypotension) Causes
Low blood pressure (hypotension) occurs when blood pressure drops below the normal range. Low blood pressure can be temporary, or it can be a chronic (long-lasting) condition.Low Blood Pressure Picture
Low blood pressure (hypotension) is pressure so low it causes symptoms or signs due to the low flow of blood through the arteries and veins. When the flow of blood is too low to deliver enough oxygen and nutrients to vital organs such as the brain, heart, and kidney, the organs do not function normally and may be temporarily or permanently damaged.
