[|Human|] I need to understand this case study: Subject 1: A 50-year-old man with no apparent health problems who is moderately active and normal weight has the following blood values: high-density lipoprotein (HDL) cholesterol = 30 mg/dL; low-density lipoprotein (LDL) cholesterol = 160 mg/dL; and triglycerides = 300 mg/dL.
[|AI|]  Hello, i have gone through your question. Thanks for using Chat Doctor. In our blood there are different kinds of fats viz. Cholesterol and triglycerides. Cholesterol have attachments of proteins on its molecules with variable density. They are low density lipoprotein(LDL) and High density lipoprotein(HDL).HDL is protective type of cholesterol, and it protects against deposition of fat in arterial wall creating blockages. LDL is the most harmful cholesterol in creating blockages in arteries. These cholesterol by themselves do not produce any symptoms. So inspire of high levels person remains apparently healthy for few years. But once blockages develop beyond certain limit it may lead to heart attack, stoke etc. Normal level of LDL should be less than 100 mg, normal level of triglycerides should be Less than 200 AMD HDL should be above 35 in males and above 40 in females.I hope This satisfies your quarry. My best wishes Chat Doctor.
