High cholesterol, also known as hyper-cholesterolaemia, often doesn’t show any clear symptoms, making it a “silent killer.” However, some signs may appear during physical activities like walking. These symptoms are often linked to Peripheral Artery Disease (PAD), a condition associated with increased cholesterol levels.
Who Is at Higher Risk?
People more likely to develop high cholesterol include below categories:
-
Family history of the condition
-
A diet high in unhealthy fats
-
Smoking or excessive alcohol consumption
-
Lack of physical activity
-
Being overweight
-
Having any other medical condition like diabetes or thyroid issues
-
Ageing, especially in postmenopausal women, can naturally increase cholesterol levels.
Warning Signs of High Cholesterol
Here are five warning signs that an individual may experience during walking and it is advised to not ignore these signs.
1. Numbness or Tingling
Restricted blood flow can cause numbness or a “pins and needles” sensation in your feet or toes, especially during physical activity. Nerves need a steady oxygen supply to function correctly, and when they don’t get it, nerve damage can occur. Chronic tingling or numbness should be checked by a doctor to prevent complications.
2. Leg Pain or Discomfort
One of the earliest signs of high cholesterol is leg pain caused by PAD (Peripheral Artery Disease). When cholesterol builds up in arteries, they become narrower, reducing the oxygen supply to muscles. This causes pain, discomfort, or tiredness in the calves, thighs, or buttocks, especially during walking or climbing stairs. Usually, the pain subsides with rest, but in severe cases, it can persist even when one is at rest.
3. Muscle Weakness
Cholesterol buildup can restrict blood flow to your leg muscles, leading to weakness. You may struggle to walk, maintain balance, or stand for long periods. Over time, poor circulation may cause muscle atrophy, making movement difficult, especially for older adults or those with additional health risks.
4. Cold Feet or Legs
Another alarming symptom of high cholesterol is poor circulation due to narrowed arteries can make one foot or leg feel colder than the other, particularly after walking. In severe cases, the affected leg may appear pale or bluish due to inadequate oxygen. Persistent coldness in the extremities should not be ignored, as it could signal significant artery blockage.
5. Changes in Skin Color
If your feet or legs appear lighter or have a purplish-blue tint, it could be due to poor circulation from high cholesterol. When oxygen-rich blood can’t reach the skin properly, it leads to discoloration. In extreme cases, this can result in cyanosis, where tissues turn blue due to a severe lack of oxygen.
High cholesterol can slow down the healing of minor cuts or injuries on the feet and legs. Poor circulation means tissues don’t get enough nutrients and oxygen to repair themselves. Wounds that take a long time to heal can increase the risk of infection or lead to serious issues like gangrene.
How to Reduce High Cholesterol Risk
-
Regular Screenings: Routine cholesterol tests can help with early detection and treatment.
-
Healthy Diet: Eat more fruits, vegetables, whole grains, and lean proteins. Limit saturated and trans fats.
-
Exercise: Regular physical activity, like walking, can help maintain a healthy weight and support heart health.
-
Quit Smoking: Avoid tobacco to keep your arteries healthy.
High cholesterol gradually impacts our heart health, it is therefore crucial to monitor the cholesterol levels regularly especially for those who are either having this condition or any other medical condition.
FAQ on High Cholesterol
What will happen if cholesterol is high?
High cholesterol causes formation of plaque in arteries, restricting blood circulation and increasing the risk of heart disease, stroke, and other health problems. This plaque can also break off and form blood clots, leading a heart attack or stroke.
What is the main cause of high cholesterol?
The primary cause of high cholesterol is an unhealthy lifestyle, including below factors:
-
Family history of the condition
-
A diet high in unhealthy fats
-
Lack of physical activity
-
Smoking or excessive alcohol consumption
-
Being overweight
-
Having any other medical condition like diabetes or thyroid issues
-
Ageing, especially in postmenopausal women, can naturally increase cholesterol levels.
Can high cholesterol be cured?
While high cholesterol can’t be “cured” permanently, it can be effectively managed and reduced to a healthy level through lifestyle changes and, if necessary, medication. High cholesterol is a risk factor for heart disease and stroke, and managing it can significantly reduce these risks.
