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.

Blood donation is a process that is carried out when a person voluntarily offers for blood to be extracted from his body. There are countless myths about blood donation that need to be squashed and awareness is the only way of doing it.

While blood donation brings multiple health benefits to both the donor and recipient, some facts are known to only a few. These facts will not only open doors to endless possibilities, but will make people feel confident about it.

Facts

Here are some lesser-known facts about blood donation- every person should know-

 


	
	Approximately 112.5 million units of blood are collected from blood donation globally.
	
	
	Around 30 million units are transfused annually.
	
	
	Any person in sound health, at least 18 years old, and weighing at least 45 kilograms can donate blood every 56 days.
	
	
	Your one unit of donated blood can save up to 3 lives.
	
	
	A, b, ab, and o are the primary blood groups. While ab is a universal recipient, o negative is a universal donor.
	
	
	The blood donation process normally takes less than 10-12 minutes.
	
	
	Donating blood does not make you physically weak or decrease your strength.
	
	
	Only 1% of india's population donates blood each year, leading to an annual deficit of two million units.
	
	
	All donated blood units are tested for diseases like hepatitis b, hepatitis c, hiv, and syphilis before transfusion.
	
	
	Red cells, plasma, cryoprecipitate, and platelets are the various types of transfusable elements derived from the blood. The procedure takes place using a method called apheresis.
	
	
	Red blood cells carry oxygen to the organs.
	
	
	Red blood cells survive for about four months in the system of circulation.
	
	
	Platelets encourage blood clotting and provide leukemia patients and other cancer patients with better treatment.
	
	
	Plasma is a pale yellow combination of proteins, salts, and water.
	
	
	Plasma is 55 percent of the volume of blood and 90 percent water.
	
	
	White cells are the chief defense of the body against infections.
	
	
	There is no alternative for blood donation as blood cannot be manufactured.
	
	
	You cannot contract aids or other infectious diseases due to blood donation.
	


Lesser Known Facts About Blood Donation

Headaches are extremely common   we all are familiar with mild or persistent throbbing ;pain. A number of conditions can result in headaches. Some of these include  


	
	Fatigue
	
	
	Lack of sleep
	
	
	Stress/tension
	
	
	An underlying condition, like migraine ;or sinusitis
	


Recent studies have revealed a lesser-known cause for headaches   ;hypertension, or what is commonly referred to as high blood pressure.

The connection between hypertension and headaches

Hypertension occurs when the force of the blood circulation in the arteries is elevated   this particular condition can lead to steady pain throughout the head, particularly at the back of the head or in forehead.

Hypertension-induced headaches usually affect both sides of the head, particularly the temple regions. However, a person may not even realize that the headaches he/she is experiencing are induced by high blood pressure.

Since hypertension is an asymptotic condition, it is often referred to as  the silent killer . When blood pressure rises above 180/110, the condition is known as  hypertensive emergency .

Different types of hypertension leading to headaches

There are three types of hypertension conditions that are followed by mild to severe headaches:


	
	Malignant hypertension- this refers to a sudden, rapid increase in blood pressure that calls for medical attention. This is more common among young adults and women with pregnancy-induced hypertension.
	
	
	Idiopathic ;intracranial hypertension- it is characterized by elevated blood pressure around the brain. Symptoms include vision problems, nausea, ;shoulder pain, thumping noise in the ears, and severe headaches.
	
	
	Hypertensive encephalopathy- this is an extreme condition of high blood pressure, which leads to swelling in the brain. A person with this condition experiences severe headache that becomes worse.
	


Uncontrolled hypertension can be dangerous   headaches induced by such a condition could also become frequent or worsen over time. However, with proper medications and certain lifestyle changes, high blood pressure can be kept under the normal measure. Once your blood pressure normalizes, the headaches will disappear in no time.

How Are Hypertension And Headaches Related?

When abnormal cells grow inside the brain and are in the form of a mass the condition is called a brain tumour. However, on the other hand, brain cancer is a disease of the brain in which cancer cells (malignant cells) arise in the brain tissue. Cancer cells grow to form a mass of cancer tissue (tumour) that interferes with brain functions such as muscle control, sensation, memory, and other normal body functions. 

 ;

Some brain tumours are cancerous while others fall under the category of non-cancerous ones.

Brain cancer is actually the abnormal growth and uncontrolled growth of the cancer cells in the brain, that forms a tumour in the brain. Tumours can be either benign or malignant.

Benign brain tumours are abnormal collections of cells that reproduce slowly and usually remain separate from the surrounding normal brain.

Malignant tumours reproduce and grow quickly. Their borders are hard to distinguish from the normal brain around them.

 

The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.

 ;

The brain tumours originate in the brain itself. Tumours start to develop if there are mutations in the dna. It is because of these mutations that cells of the brain increasingly grow and divide. Usually, in adults, the primary brain tumours are uncommon in comparison to the secondary brain tumours.


 

There are few early symptoms of brain cancer, but as the tumour grows within the confines of the skull, it causes increased intracranial pressure and exerts pressure on the brain, causing signs to develop.

Brain cancer occurs when there is an uncontrolled growth of cancer cells in the brain that form a malignant brain tumour. The underlying cause of primary brain cancer, cancer that begins in the brain, is not known. Secondary brain cancer is caused by a cancer of another organ in the body, such as the breast, prostate, kidney, skin, or bone, that has spread to the brain.


 

What Is The Significant Difference Between Brain Tumour And Brain Cancer?

People with sickle cell disease often experience myriad symptoms of the disease that can be controlled by the right nutrition. Reports suggest that nutrition is an increasingly significant factor to prevent symptoms such as slow growth, lower body mass, joint issues, infections, pain crises, and anemia.

There is a greater than the typical requirement for both calories and micronutrients.

The nutritional requirement of a sickle cell patient emphasizes more on vegetables, fruits, whole grains, and more similar food items. These can prevent any deficiencies in the body and also decrease any chances of disease exacerbation.

 


	
	High-calorie nutrient-dense diet
	


The usual energy intake in a sickle cell patient is normally lower than the average values. It is a case even when the condition is asymptomatic where the requirement drops to half the level. As a result, people with sickle cell diseases (especially kids) are at higher risk for impaired growth and considerably lesser fat and fat-free mass, with obesity also posing a risk. It is suggested to have adequate energy supplements in the diet to reach the minimum sufficient requirement of the body that can be done only by proper nutritional assessment.


	
	Adequate fluids
	


Avoiding dehydration is another significant factor to avoid any severe symptoms of sickle cell disease. Sickling of the erythrocytes aggravates in patients who perform hardcore physical work in the heat without drinking enough fluids. This leads to dehydration and can even result in constipation.


	
	Micronutrients
	


Micronutrient deficiencies can be found in sickle cell patients up to a great extent. Several vitamins and minerals like vitamin a, b6, c, e, carotenoids, zinc, and magnesium are often found in fewer numbers in scd patients. A significant drop in blood-antioxidant status may result in acute chest syndrome. The supplementation of these vitamins and minerals can reduce the number of sickled cells in the body. Plant phenols and flavonoids may also help in lowering oxidative stress.


	
	Calcium-rich food
	


Getting plenty of calcium-rich food like dairy products, leafy vegetables, cereals, and fruit juices aids the child's growth and development. This may lead to a stronger physical structure and a greater resistance to the disease.


	
	Omega-3 fatty acid
	


There are reduced proportions of omega-3 polyunsaturated fatty acids in sickle cell patients. These acids aid the fluidity of red blood cell membranes. As a result, they prevent sickle cell crises. Supplemental docosahexaenoic (dha) and eicosapentaenoic (epa) have shown numerous therapeutic benefits in scd patients.

Role Of Nutrition In Sickle Cell Disease

Potassium is an essential mineral that helps in healthy functioning of your body   it helps in muscle contractions, fluid balance, and nerve signals. Your body receives the required amount of potassium from specific food sources and processes the same. The excess potassium is eliminated from the bloodstream by your kidneys.

Under normal circumstances, your blood levels should be between 3.5meq/l and 5.5meq/l for potassium to carry on these functions. Healthy kidneys play a vital role in keeping the potassium levels in check.

In case your kidneys are unable to remove excess potassium, it may get stored in your blood, leading to a condition known as hyperkalemia.

The link between your kidneys and potassium

The mineral potassium and your kidneys share an intricate relationship. If the levels of potassium in your blood are too high, it can pose a threat to your cardiac condition   leading to a ;heart attack or ;irregular heartbeat.

Hyperkalemia occurs when the kidneys fail to function properly. Your kidneys work to balance the amount of potassium consumed with that, which is eliminated through urine. Your body takes in potassium through the foods and drinks you consume. In the initial stages of your kidney disorder, they may be able to make up for high levels of potassium. However, as your condition worsens, they may be unable to eliminate enough of the mineral from the body.

How to find out if you have high potassium levels

The only way to figure out if your potassium levels are healthy or too elevated is to go for a blood test. The test measures the level of potassium in the bloodstream.

As long as your kidneys are healthy, your potassium levels will be under control. Therefore, if you have hyperkalemia, or if there are chances of you getting it, you may have to cut back on foods that are high in potassium content. Besides, you will have to rely on diuretics and potassium binders.
