Stroke is one of the deadliest diseases. It is the second leading cause of death. Almost 5.5 million people suffer from this disease every year. Our body needs oxygen which is carried by the blood to all organs of the body. If any organ does not get oxygen, then it will lose its functionality. The provision of oxygen is necessary for every part of the body.
The brain is also an important part and it is the central organ of the nervous system. It also requires oxygen. If the provision of blood ceases, then a stroke occurs. Hence, It occurs when the brain does not get oxygen for its function. In this case, the brain cells start to die due to the shortage of necessary nutrients. The interruption of blood supply can be due to blood clotting or blockage in the blood vessels.
Stroke is one of the most vulnerable life taking diseases. Therefore, we are going to discuss everything about it in this article. We will tell you the types, symptoms, and preventions.
Types of Stroke
The main reason for the occurrence of stroke is an insufficient supply of blood/oxygen to the brain. The types are based on the reason due to which the supply of blood faces hindrance. There are two main types of strokes which are,
- Ischemic Stroke
- Hemorrhagic Stroke
This stroke occurs when the path of blood is blocked by blood clotting. The flow of blood is sometimes blocked by debris or plaque as well. Plaque is formed by the deposition of fatty substances. The main reason is high blood pressure. In this stroke, the flow of blood is either blocked or reduced. The brain gets a low amount of oxygen and nutrients. It is very common and normally 80% of the strokes are Ischemic Stroke.
Ischemic stroke can be further classified into two types which are Thrombotic stroke and Embolic stroke.
A thrombotic stroke is due to the blood clot in a blood vessel that carries blood to the brain. This clot is near the brain.
Embolic stroke is due to the clot that is formed away from the brain. The clot can be in other organs of the body such as the heart or chest. This clot stops or reduces the flow of blood to the brain.
Hemorrhagic stroke occurs when the blood vessels are leaked. This leakage can be due to weak walls of the vessels or due to an accident. The blood from the leakage damage the cells around it. Some of the cells which are away from the blood spill are suffered by the shortage of blood supply. The cause of this stroke can be high blood pressure. Therefore, high blood pressure is first controlled in this stroke for the treatment. There can be surgery to fix the ruptures in the blood vessels. Hemorrhagic stroke is less common than ischemic stroke.
Symptoms of Stroke
There are few common symptoms which are,
- Headache: Due to low blood flow there can be a headache. This headache can be short term or long term. In Transient Ischemic Attack, the flow of blood is blocked temporarily. Therefore, the headache can go away within hours.
- Vomiting: There can be vomiting with a headache as well.
- Weakness: You may feel weakness in your arms and legs. It can be hard to move your hands and arms.
- Vision: There can low vision in both the eyes.
- Dizziness: The patient may lose balance while walking.
- Problems in speech
- Confusion and Hallucination
Preventions of Stroke
Since it is a deadly disease, we should be aware of its preventions. The preventions are,
Controlling the Blood Pressure
Blood pressure is one of the major causes; therefore, it should be in control to avoid it. Sometimes high blood pressure can damage the weak walls of blood vessels. The blood pressure should be at normal level. Low blood pressure does not cause this disease, but it is not good for health as well.
Exercise helps to maintain the blood flow in the parts of the body. By Exercise, we do not mean heavy weight lifting or bodybuilding. You should do cardio and aerobic exercise as it ensures the blood flow to all parts of the body.
Say No to Alcohols and Cigarettes
Alcohols and cigarettes are very dangerous to health. Therefore, they should be avoided to reduce the risk of many deadly diseases.
Control your weight
The weight should be in control. Check your BMI and maintain your weight at normal. It can reduce the fats in your body and the risk of stroke. You should maintain a healthy diet as well while controlling the weight.
Diabetes patients should keep an eye on the sugar level. The sugar level should be in control.
The common treatments are,
- Anti-platelets and Anticoagulants: These drugs reduce the clotting done by platelets. Platelets are the blood cells that are responsible for clotting. These drugs also reduce the growth of clots.
- Surgery: When there is no effect of medicines, then doctors do surgery to remove the blood clots and plaques.
Which kinds of people are at higher risk of stroke?
Stroke has some risk factor related to the age and health of the person.
- Young and old, both can suffer from it. But older people are at a higher risk.
- Men are more likely to get this disease as compared to women.
- Obese people are more likely to have a plaque in their blood vessels; therefore, they are at a higher risk.
- Heavy intake of drugs and alcohol can be the cause.
- People with high blood pressure are also at high risk.
- Diabetes and high cholesterol also increase the risk of getting it.
Stroke is one of the deadliest diseases in the world. It is responsible for killing millions of people every year in the world. According to statistics, this disease has killed nearly 15 million people in the world in the year 2016. It is better to prevent this disease at first. The weight, cholesterol, diabetes and blood pressure should be in control. Aerobic and cardio exercises are good to reduce the risk. If you have any symptoms of the stroke, then immediately visit the nearest medical center.
