Lesser Known Facts About Blood Donation

World sickle cell day is observed annually on the 19th of june to raise awareness of sickle cell-related diseases. It is observed to increase people's knowledge and the understanding required to face the challenges posed by the disease.


 

What is sickle cell disorder (scd)?

Sickle cell disorders or sickle cell diseases are genetic blood disorders that cause an abnormality in the red blood cells. The rbcs turn into sickle-shaped cells that stick together and block the blood flow in the body.


 ;

Types

There are four major classifications of sickle cell diseases-


	
	Hemoglobin ss disease
	
	
	Hemoglobin sc disease
	
	
	Hemoglobin sb+ thalassemia
	
	
	Hemoglobin sb 0 thalassemia
	



 

Symptoms

One can start noticing symptoms of sickle cell in a patient at around 6 years of age. However, they can differ from person to person. Some of the most typical symptoms are-

 ;


	
	Anemia
	


A shortage of red blood cells occurs due to the excessive early dying in 10-20 days. It leads to an oxygen shortage in the body.


	
	Excessive pain
	


Blockage of blood flow due to the change in shape leads to periodic cycles of pain in the body.


	
	Swelling in the body
	


As the blood circulation becomes irregular, swelling becomes a regular phenomenon.


	
	Infections
	


Sickle cell can be damaging to the spleen. It increases the risk of ailments in the body that can be prevented only by antibiotics.


	
	Delayed puberty
	


Oxygen and nutrients carried by the blood are required for growth. As a reason, irregular blood flow can lead to slow growth or delay in puberty.


	
	Vision issues
	


Infected blood vessels carrying blood to the eyes can cause damage to the retina. It can lead to visual problems.


 

Traits and treatment

As sickle cell is genetic, it is suggested to take a test that can detect any trait of the disease. It can prevent any life-threatening risks to the newborn. However, we don't have a complete cure for sickle cell disorders. There are preventive measures that reduce the adversity of the disease to an extent. Procedures like blood transfusions help greatly in minimizing the effects of the disorder.

Environmental factors play a quintessential role in affecting our health. Fresh air, fresh food and fresh water, not only strengthen our body and mind but also make our life worth living. Contrary to this bad environment hampers the quality of life. This is the main reason why people from hill stations or the countryside seem to be healthier than those living in polluted urban cities. Following are the environmental factors that affect your health:

Polluted air

The health effects of polluted air are several. Not many people know that one-third of the deaths are caused because of strokes, lung cancer and heart failure. Air pollution is the chief reason behind these chronic ailments. The other life-threatening diseases caused by polluted air is- asthma or bronchitis. Smoke from machines, vehicles outside, and stoves, the burning of fuels inside can cause breathing problems and wheezing. 

Dirty environment

A dirty environment often leads to the breeding of insects and bacteria that become carriers of life-threatening diseases such as dengue, typhoid, diphtheria, malaria, and so on. Most of the diseases mentioned here are caused by mosquitoes that thrive on stagnant water.

Toxic food ;

The environmental quality of a region has a direct impact on the food produced in that area. Both vegetarian and non-vegetarian food faces the danger of becoming toxic if the environment it is being grown in is polluted. For eg- chemical wastes that are often dumped in water bodies cause the seafood in that area to become highly toxic.

Chemical pollutants

Cancer nowadays is becoming a household disease. The major reason behind this is that technological development has brought new categories of pollutants. Many of these contain chemicals and compounds that are carcinogenic in nature. This ultimately leads to the development of cancer in most people. 

Climate change and natural calamities

Change in climate disrupts the functioning of nature in many ways that further impact the health of humans. These changes include- the natural temperature of the planet, heavy rainfalls and sandstorms. The numerous impacts of climate may result in a high risk of nervous and respiratory diseases. ;

Hence protecting the environment is extremely important for the life of a human being. The change will come after taking small steps. Numerous small steps can really make a difference.

Environmental Factors That Affect Health

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.

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.
