Atherosclerosis refers to a medical condition in which the arteries become hardened and narrowed due to the accumulation of cholesterol plaque in the walls of the artery, obstructing the flow of blood.

What are the causes?

Atherosclerosis is a slow but progressive disorder that starts with the damage of endothelium   cells lining the interior surface of lymphatic and blood vessels. This allows bad ldl cholesterol to build up in the artery walls. Over time, a plaque made of calcium, macrophages, and cholesterol grows to a certain size to clog up arteries, disrupting blood flow around the body.

Other factors leading to atherosclerosis to include  

High blood pressure

High levels of triglyceride in the blood

High cholesterol levels

Certain medical conditions   diabetes, obesity, insulin resistance

Smoking/use of tobacco

Inflammatory conditions like lupus and arthritis

Symptoms of atherosclerosis

Atherosclerosis may develop in childhood or during adolescence. Mild conditions may not reveal observable symptoms unless the arteries are clogged, and blood supply to the tissues and organs are restricted.

Signs of moderate to severe atherosclerosis depend on the affected arteries   it could be the arteries leading to your brain, your heart, legs and arms, or the kidney. The symptoms of atherosclerosis include  

Weakness and fatigue

Difficulty breathing/concentrating

Headaches

Facial numbness

Paralysis

Vomiting

Chest pain

Anxiety

Loss of appetite

Swelling in the feet and hands

If any of the above symptoms seem familiar to you, consult a doctor right away for treatment.

Can atherosclerosis be prevented?

The best way to avoid cholesterol plaque from building up in the artery walls is to prevent the onset of atherosclerosis with these preventive measures.

Eat healthy   avoid eating foods that are rich in saturated fats   red meat, butter and cheese. These increase your cholesterol levels drastically. Instead, include foods that contain unsaturated fats, like avocados, olive oil, fatty fish, nuts and seeds because these help to keep ldl or bad cholesterol levels down.

Stay active   exercising and staying active can help regulate your cholesterol levels and prevent certain conditions that might put you at risk for atherosclerosis.

Quit smoking   people who smoke should quit smoking because it is a major risk factor for atherosclerosis   it increases blood pressure, which in turn, affects your cholesterol levels.

Atherosclerosis can lead to complications. With precautionary measures and proper treatment, the condition can be avoided.

When abnormal cells grow inside the brain and are in the form of a mass the condition is called a brain tumour. There are various types of brain tumours that exist. Some of the brain tumours which exist are malignant or cancerous while other may be non-cancerous. A brain tumour can begin in any part of the brain and spread to other parts of the body or vice-versa. The growth rate of brain tumours is different for each individual suffering from it. As per studies, every 2 in 1, 00, 000 people are said to be affected by a brain tumour in india. However, it may come as a relief to some as not all brain tumours are cancerous or life-threatening. Some are benign tumours and seldom pose any threat to the affected individual.

 

Types of brain tumor

Brain tumours may be primary or secondary.

Primary brain tumour

In this type of brain tumour, the abnormal mass of cells that originated in the brain does not metastasize to the other organs. Based on their location in the brain, the primary brain tumours may be of the following types.


	
	Gliomas: one of the most common types of primary brain tumours, gliomas can have their origin in the spinal cord or the brain. Some of the common types of gliomas include astrocytomas (originates in the cerebrum of the brain), glioblastomas (these tumours form from the astrocytes which form the supportive tissues of the brain), ependymoma (these develop from the ependymal cells which are present within the cns), oligodendrogliomas (these tumours are found to arise from the oligodendrocytes).
	
	
	Schwannomas: also called acoustic neuromas, these primary brain tumours form on the nerves that play an important role in regulating the balance and hearing from the inner ear to the brain.
	
	
	Meningiomas: these types of tumours are usually benign and have their origin in the meninges (membranes surrounding the spinal cord and the brain).
	
	
	Primitive neuroectodermal tumours (pnets): primitive neuroectodermal tumours (pnets) are rare malignant tumours that originate from the fetal (embryonic) cells in the brain.
	
	
	Pituitary adenomas: as the name suggests, these tumours arise from the pituitary gland located at the base of the brain.
	
	
	Medulloblastomas: common among children, these malignant primary tumours develop in the brain (lower back) and gradually spread via the spinal fluid.
	


Other types of primary brain tumours include craniopharyngiomas and germ cell tumours.

Secondary brain tumours ;

Unlike the primary brain tumours, these tumours have their origin in the other body parts and organs (mostly in the lungs, skin, colon, breast, and kidney) and then gradually metastasize to the brain. Secondary brain tumours are found to be more common.

 

What Are The Different Types Of Brain Tumours?

A brain tumour is a life-threatening situation. Most of the symptoms of the brain tumour are alike, but not all tumours are malignant. The most common type of brain tumour is meningioma. You may even don t need surgery in this case as they are really not dangerous or life-threatening.

 

Here are some of the facts you should know about meningioma:

 ;

Meningioma can develop in numerous locations

 

Cells in the meninges, the lining of the brain and spinal cord, give rise to these tumours. In fact, they are not brain tumours at all, because they are not caused by the altered brain cells. ;

However, they continue to grow inside your sull, indicating that you should now take immediate steps. Meningioma can produce brain tumour symptoms if it grows or creates swelling that presses against the brain or other tissues in the skull.

 

Meningioma symptoms vary depending on the size and location of the tumour

 ;

Meningioma can cause vision-related issues, headaches or seizures which are all common signs of a brain tumour. A headache, even a strong one, is seldom an indication of meningioma or any other type of brain tumour on its own. 

 ;

Other tumour sites can influence your sense of smell, vision, hearing and even the pituitary gland s function.

 

Meningioma diagnosis usually happens when the doctor is looking for some else

 ;

The discovery of a tumour on a ct scan or mri while investigating the patient for another cause, such as a head injury or another neurological condition, is called an accidental diagnosis. When a doctor identifies a meningioma, you will undergo additional testing to determine how the tumour will behave. A neurosurgeon will decide whether to remove the tumour or just monitor it to see whether it grows based on these findings. 

 ;

Majority of meningioma does not spread

 

Being diagnosed with meningioma, especially a large one, might be shocking, but these tumours are usually non-dangerous. Tumour cells are unlikely to spread to other sections of the body as a result of this. ;

Meningiomas, on the other hand, can grow silently for years without creating any difficulties and they can grow to be enormous.

Blood types that are needed most

It s good to donate if you re healthy. However, there s always a need for specific blood and plasma which are universal and can be used when a patient blood type is unknown. For newborn infants or if a patient's particular blood type is unavailable.

 ;


	
	Type o negative blood is always needed because it can be used in patients regardless of their blood type.
	
	
	Type ab positive plasma can also be transfused to patients with other blood types. 
	


 ;

Donations are constantly needed

Because of their short shelf life of 5 days after being collected, platelet donations are constantly by the blood blank. Red blood cells also have a short shelf life and needed to be used within 42 days after the collection. Cryoprecipitate and plasma can be frozen and stored for up to a year after donation.


 

Some misconceptions about blood donations


	
	The donor will not experience any kind of pain while donating. ;
	
	
	There will be no scarcity of blood in the body after donating the blood as even after the donation the body will have a surplus quantity of blood.

The A, B and C of Hepatitis

Air pollution affects the overall health of a human being. Whether it comes out of exhaust fumes from cars and factories or smoke from burning stubble air pollution, it is a cause of major concern. The effects of this can be seen in the growing number of asthma and other respiratory diseases. These diseases affect adults and children alike, however, it is the younger generation and elderly people who are more susceptible. Hence, it is extremely important to care about the quality of the air you breathe in. 


 ;

What is the significance of the air quality index (aqi)?

The air quality index is a visual representation of pollutant levels in the air around you. A quick glance at this colour coded map can tell you if the air outside your home is likely to harm you or not. The code is broken down into 6 levels ranging from green which signifies minimal impact to red which marks pollution levels that can harm a healthy person and seriously impact those who are already ill. The higher the aqi, the higher the level of air pollution.

 

What are the steps to reduce air pollution?

Simply talking about how there need to be stricter laws about car emissions and the burning of waste will not help you. Here are a few things you can do to protect yourself and your family from the ill-effects of air pollution.


	
	Carpool: exhausts from cars and other vehicles are one of the biggest causes of air pollution. Do your part to reduce air pollution by restricting the amount you use your car. Try taking public transport to work or carpooling with colleagues. Similarly, avoid making individual trips every time you need something from the market. Make a list and when it s long enough, then step out.
	
	
	Limit indoor pollution: do not smoke indoors. When cooking, keep the exhaust fan on so that the smoke produced does not collect indoors. Avoid spraying air fresheners etc. While they may temporarily make the air smell fresh, in the long run, they contribute to air pollution.
	
	
	Use public transport try to use public transport and avoid the use of personal vehicles.
	


How to protect yourself from air pollution


	
	Refrain from morning walks routines to later hours.
	
	
	Use n95/99 face masks whenever you step out.
	
	
	Use air-purifying plants to purify the air around your surroundings.
	
	
	Ventilate your kitchen, and bathroom to keep yourself away from air pollution.
	
	
	Restrict outdoor activities for kids if there is a high level of air pollution
	
	
	Use air-purifiers in your surroundings.
	
	
	Try to take steam with a few drops of eucalyptus oil every day.
	
	
	Keep your car s environment fresh.
	
	
	Ventilate your home, open your windows and doors and allow the air to circulate during mid hours.
	
	
	Eat jaggery (aka gurr) to flush out pollutants from your lungs.
	
	
	Consume a diet rich in vitamin c, omega fatty acids
	


Hence, the other way to cut down this pollution is by bringing significant lifestyle changes in our daily living. Cutting down the number of diesel and petrol vehicles can also prove helpful. People should shift to cng and electric vehicles for daily commuting. These efforts, if practiced on a regular basis, can bring a huge decrease in pollution.

Air purifiers can also be a healthy option for indoor purposes.
