Here, I am giving some light on the modifiable and non-modifiable diseases, which are harmful to our health.
Understanding the factors that influence our health can help us make better choices and reduce the risk of many diseases.Some risk factors can be changed through lifestyle and medical care, while others cannot be changed. These are broadly called modifiable and non- modifiable risk factors.
Coronary heart disease is the major killer in the world today. These killer risk factors can be controlled if we are aware of the risk factors of CHD. The factors which can change are modifiable and those that can’t are non-modifiable.
What are Risk Factors?
A risk factor is a characteristic, habit, condition, or exposure that can increase the likelihood of developing a disease or health problem. Having a risk factor does not mean that a person will definitely develop a particular disease – it simply means the risk may be higher.
Non- modifiable risk factors
Non-modifiable risk factors are characteristic that generally cannot be changed. However, knowing about them can help people take appropriate preventive measures.
Example include:
1) Increasing age– Incidence of CHD increases with age, majority of patients being in the 50 plus.
2) Sex– Men have a greater risk of CHD than women and they have attacks earlier in life.
3) Hereditary — Children of parents with CHD are more likely to develop it themselves. The lifestyle of the family, presence of other risk factors like obesity, hypertension, and diabetes in the family increase the risk.
4) Family history – having close relatives with certain diseases may increase an individual’s risk.
5) Ethnicity or population background – certain conditions may occur more frequently in particular populations because of genetics, environmental or social factors.
6) Previous medical history – A previous disease or health event may increase the likelihood of future health problems.
Modifiable risk factors
Modifiable risk factors that can often be changed, reduced or managed through lifestyle changes, preventive care or appropriate treatment.
Common examples include:
1) Smoking — about 30% of the smoking-related deaths are due to CHD and smoking is responsible for about 20% of all death from CHD. Smokers who have a heart attack are more likely to die. Apart from the smokers, the people around the smoker( passive smokers) are also at the increase risk.
2) Hypertension — The risk of CHD increases continuously with increasing blood pressure. Hypertension damages the endothelial lining of the arteries making them more susceptible to atherosclerosis and vasospasm.
3) High cholesterol levels — the risk of CHD rises as blood cholesterol levels increase. High blood cholesterol levels also increase the incidence of death due to CHD. The source of cholesterol can be exogenous( from the diet) or endogenous( produced in the body mainly by the liver). Today, people are eating an increased amount of non-vegetarian foods or junk foods and contributing to exogenous source of cholesterol.
4) Obesity– people who have excess body fat are more likely to develop CHD even if they have no other risk factors. Obesity is directly linked with CHD because it influences blood pressure, blood cholesterol and triglycerides and makes diabetes more likely to develop. Central obesity which is associated with increased abdominal fats has a greater adverse effect on associated risk factors and actual risk of CHD.
So, there is a strong positive relationship between the degree of obesity and the presence of hypertension, hypertriglyceridaemia, hyperinsulinemia and low level of HDL – cholesterol.
5) Physical Activity — Physically inactive people have a higher tendency to develop obesity, diabetes, low blood viscosity and low HDL cholesterol and all are at an increased risk of developing CHD.
People who exercise regularly have a greater cardiorespiratory reserve. Regular exercise is an excellent stress reliever.
6) Diabetes– Diabetes is a strong risk factor in women. Both IDDM and NIDDM are associated with a markedly increased risk of CHD. Diabetes increases triglycerides, reduce HDL cholesterol, damage the endothelium and promote smooth muscle proliferation in the arteries and increase transport of cholesterol into smooth muscle cells.
7) Stress— In daily life, we are under great stress these days. People are facing problems even to get their basic needs. The cost of living is increasing and people find it difficult to make their ends meet. The families are breaking and the responsibilities are not being shared. People under stress tend to overeat, start smoking or some more than they otherwise would. Stress can increase blood pressure, heart rate and adverse effects on coagulation and fibrinolysis.
A negative mind never gives you a positive life.
8) Oral contraceptive pills – there is evidence to suggest that the pill damages the arteries and increase the incidence of CHD, especially when taken 5 years or more. Risk is greater in women above 35 years old and in the presence of other risk factors.
9) Poor Sleep and chronic stress – Improving sleep habits and developing healthy ways to manage stress may support overall health.
Why Understanding Both Matters
We cannot change our age, genetics, or family history.However, these factors don’t mean that our health is predetermined.
For example,someone with a family history of heart disease may benefit from paying particular attention to physical activity, nutrition, blood pressure, cholesterol, smoking and regular medical check-ups.
The goal is not to worry about every risk factor but to focus on the factors that can be changed and manage those that cannot.
Takeaway
Health is influenced by a combination of genetics, environment, lifestyle and medical factors.Non-modifiable risks factors help us understand our background risk, while modifiable risk factors provide opportunities for prevention.
Small, consistent changes-such as eating a balanced diet, staying physically active, avoiding tobacco, getting adequate sleep and following appropriate medical advice- can contribute to better long-term health.
Remember: knowing your risk is not a reason for fear, it is an opportunity to take preventive action.
So, hope now you will take care of yourself, your families and friends.
