cholesterol in the morning
Informed by recognized medical guidance
Overview
High cholesterol is a condition where you have too much of a fatty substance called cholesterol in your blood. It often has no symptoms but can increase your risk of heart disease and stroke. Doctors usually ask you to have a blood test in the morning after not eating for 8-12 hours (fasting) because food can affect your cholesterol levels.
Key facts
- High cholesterol itself usually has no symptoms, so many people don't know they have it.
- You can lower high cholesterol with a healthy diet, regular exercise, and sometimes medication.
- Family history and age are important risk factors.
Yes, high cholesterol is very common. In the UK, around 2 in 5 adults have high cholesterol (NHS).
Anyone can have high cholesterol, but it becomes more common as you get older, especially after age 40. You are at higher risk if you are overweight, eat an unhealthy diet, smoke, or have a family history of high cholesterol.
Symptoms
- Chest pain or discomfort that does not go away
- Shortness of breath
- Sudden numbness or weakness on one side of the face, arm, or leg
- Slurred speech or difficulty speaking
- ⚠Feeling dizzy or lightheaded
- ⚠Unexplained extreme tiredness
Common symptoms
- High cholesterol does not usually cause any symptoms on its own. That is why it is often called a 'silent' condition.
Symptoms in children
- High cholesterol in children is rare, but if a child has a strong family history of very high cholesterol, they may need to be tested.
Symptoms in older adults
- Older adults with high cholesterol typically have no symptoms. Routine blood tests are important for detection.
Causes
Main causes
- Eating a diet high in saturated and trans fats (found in fried foods, processed meats, and baked goods)
- Not being physically active enough
- Smoking cigarettes
- Drinking too much alcohol
Risk factors
- Family history of high cholesterol or early heart disease
- Being overweight or obese
- Age – risk increases after 40
- Having diabetes, high blood pressure, or an underactive thyroid
When to see a doctor
See a doctor urgently if:
- Call emergency services immediately if you have chest pain or signs of a stroke (like sudden weakness or slurred speech).
Book a routine appointment if:
- All adults should have a cholesterol check at least every 5 years. In the UK, the NHS Health Check offers this for people aged 40 to 74.
- Talk to your GP if you have a family history of high cholesterol or early heart disease.
Diagnosis
A simple blood test called a lipid profile, usually done in the morning after fasting (no food for 8-12 hours, only water).
Tests that may be done
- Total cholesterol
- LDL (bad) cholesterol
- HDL (good) cholesterol
- Triglycerides (another type of blood fat)
What to expect at your appointment
A nurse or phlebotomist will take a small blood sample from your arm. The test is quick and results are usually ready within a few days. Your doctor will explain what your numbers mean.
Treatment
Treatment aims to lower your cholesterol levels and reduce your risk of heart disease and stroke. It combines lifestyle changes and, when needed, medication.
Self-care at home
- Eat a heart-healthy diet – plenty of fruits, vegetables, whole grains, lean proteins, and unsaturated fats like olive oil and nuts.
- Get at least 150 minutes of moderate physical activity each week (e.g., brisk walking, cycling).
- If you smoke, seek help to quit. Limit alcohol to recommended amounts.
Medical treatments
If lifestyle changes are not enough, your doctor may prescribe medication from a class called statins, which lower cholesterol production by the liver. Other options include medicines that reduce absorption of cholesterol from food or newer injectable treatments. Your doctor will choose the right approach based on your overall health.
Living with this condition
Managing high cholesterol is an ongoing process. It involves regular check-ups, taking medication as prescribed, and sticking to healthy habits. Most people can successfully control their cholesterol and lower their risk.
Lifestyle tips
- Keep a food diary to track your meals and identify areas for improvement.
- Take your medication exactly as your doctor advises – never stop without consulting them.
- Monitor your cholesterol with regular blood tests as recommended by your healthcare team.
Diet and exercise
Aim for a diet low in saturated fats (like red meat, butter, cheese) and high in unsaturated fats (like avocados, nuts, fish). Combine this with daily activity – even a 30-minute walk can help. Your GP or a dietitian can give personalised advice.
Mental health and emotional wellbeing
Worrying about your cholesterol or heart health is normal. It can cause anxiety or stress. Remember that taking small steps can make a big difference. If you feel overwhelmed, talk to your doctor or a counsellor.
Prevention
You can reduce your chances of developing high cholesterol by maintaining a healthy weight, eating a balanced diet low in saturated fats, staying physically active, not smoking, and limiting alcohol.
Screening programmes
Routine cholesterol checks are recommended. In the UK, the NHS Health Check for people aged 40-74 includes a cholesterol test. If you have a strong family history, your doctor may suggest testing earlier.
Complications
If left untreated
- Hardening and narrowing of the arteries (atherosclerosis)
- Heart attack
- Stroke
- Peripheral artery disease (poor blood flow to the legs)
Long-term outlook
With proper treatment and lifestyle changes, most people with high cholesterol can significantly reduce their risk of heart disease and stroke. Many live long, healthy lives. It is never too late to make changes for the better.
