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-

Lesser Known Facts About Blood Donation

Abstract

Background: it is essential to have an understanding of life expectancy and risk factors among patients with sickle cell disease (sickle cell anemia, hemoglobin diseases, and thalassemias). These are required to counsel the patients, target treatment, and plan the right clinical trials.

 

Methods: a research followed 3764 people ranging from birth to 66 years of age and suffering from scd. The procedure was done to understand the life expectancy and calculate the average age at death. Moreover, the study understood the reasons for the death in all 209 adults. It used the proportional-hazards regression analysis to know the risks for an untimely death in adults with sickle cell anemia.

 ;

Results: when the results for young kids and adults with sickle cell anemia were observed, it was found that the average age at death was 48 for women and 42 for men. Moreover, suffering from hemoglobin c disease had an average mortality age of 60 for men and 68 years for women.

 

In people with sickle cell disease, 18% of deaths took place in patients with mainly renal organ failures. 33% of the tested patients were medically free of organ failures but episodes of pain crisis took their life. Out of these patients, 78% experienced chronic pain, chest syndrome, or both, while 22% suffered a stroke that took their lives.

 ;

Clinical modeling showed that people with sickle cell anemia faced acute chest syndrome, seizures, kidney failure, a white-cell count of over 15, 000 per cubic mm, and a low hemoglobin level were related to a risk of early death.

 

Conclusions: results suggested that 50% of patients with sickle cell anemia lived beyond the age of 50. A huge share of those who lost their lives suffered no noticeable chronic organ failure. However, most of them died due to acute episodes of pain or stroke. Early death was seen highest among patients who had symptomatic disease. High levels of fetal hemoglobin suggested improved chances of survival and are assumably a credible source to foresee the risks and other factors related to adult life expectancy.

Life Expectancy And Risk Factors Involved In Sickle Cell Disease

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.

 

Things You Should Know About Most Common Brain Tumours

Hepatitis is a condition that affects the liver by causing inflammation which is a common outcome resulting from a viral infection. While different types of hepatitis diseases are caused by different causes, there are some reasons like medications, toxins, alcohol, and drugs that are typically known.

 

Types

The five common types of viral hepatitis are hepatitis a, b, c, d, and e.

 ;


	
	Hepatitis a
	


Hepatitis a is the result of an infection caused by the hepatitis a virus. This type of hepatitis is an acute disease.

 


	
	Hepatitis b
	


The hepatitis b virus causes hepatitis b. This is often a chronic disease that lasts longer.

 ;


	
	Hepatitis c
	


Hepatitis c comes from the hepatitis c virus. It is one of the most common bloodborne infections in the world. It is a long-lasting condition.

 


	
	Hepatitis d
	


This is a not so commonly found form of hepatitis that only occurs in hepatitis b infected people. This virus not only causes liver inflammation but also cannot be contracted without an existing hbv infection.

 ;


	
	Hepatitis e
	


Hepatitis e is waterborne. Hepatitis e virus infection is responsible for it. It is generally acute but can be severely chronic for pregnant women.


 

Causes of viral hepatitis

It is true that different types of viral hepatitis infections are caused by distinct modes of transmission. Here are the causes of a hepatitis infection:

 ;


	
	Hepatitis a- when a person is exposed to the hepatitis a virus through food or water.
	


 


	
	Hepatitis b- when an individual comes in contact with hepatitis b virus through the transmission of bodily fluids like blood, semen, etc.
	


 ;


	
	Hepatitis c- when someone gets infected with the hepatitis c virus through the contamination of bodily fluids.
	


 


	
	Hepatitis d- when a person is exposed to hepatitis d virus-infected blood, it causes this disease.
	


 ;


	
	Hepatitis e- when a person comes in contact with the hepatitis e virus through water or food.
	


 

Causes of non-viral hepatitis

Although hepatitis is commonly caused due to an infection, other factors can also be reasons to cause hepatitis.

 ;

Alcohol

Excessive alcohol can lead to liver damage, causing inflammation. It can also be called alcoholic hepatitis. The alcohol impacts the liver cells directly. Moreover, it can also cause cirrhosis or even permanent liver failure.

 

Autoimmune system response

In rare cases, the immune system of a person attacks the liver itself. It leads to inflammation that can be mild to severe according to the infection. Moreover, it s more common in females than in males.

How Is Hepatitis Caused And Some Common Types?

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.

Why Should You Care About Air Quality?

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.
