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

What are the different types of sickle cell disease?

Sickle cell disease or sickle cell disorder is a term often used to talk about a group of diseases affecting hemoglobin. It is the oxygen-carrying element of blood that makes up 2 alpha globins and 2 beta globins. Sickle cell disease happens due to beta-globin mutation and depending on the abnormality in mutation.

Types-
Sickle cell diseases can be of many types depending on the gene mutation in the blood. Some of the common types are-

Sickle hemoglobin s disease (ss)
Hemoglobin ss disease or sickle cell anemia is the most popular type of scd. It takes place when hemoglobin s gene mutation is inherited from both mother and father. In simple words, it happens when the child inherits one substitution beta-globin gene from each parent. In this type, the body only produces hemoglobin s. It is mostly found in people of african and indian origin.

Sickle hemoglobin- c disease (sc):
Patients with sickle hemoglobin sc disease have a moderately dissimilar swapping in their genes of beta-globin. Here, both hemoglobin c and hemoglobin s are inherited from each parent. It may cause similar symptoms like anemia but remains relatively l. People of west african and mediterranean origin are more prone to this.

Hbs beta-thalassemia
People with this type of scd inherit one sickle cell gene s and one gene for beta-thalassemia from each parent. Zero and plus are the two common types of beta-thalassemia. While beta 0 thalassemia usually takes a severe form, beta + thalassemia is a milder form of the disease.

Sickle beta-zero thalassemia
Beta-zero thalassemia takes form when the child inherits the beta s gene from one parent and beta 0 thalassemia gene mutation from the other. With similar symptoms to anemia, it is a slightly severe form of beta-thalassemia.

Sickle beta-plus thalassemia
Substitutions in both beta-globin genes take place in patients with sickle beta thalassemia (sb) disease. This may even lead to the requirement of blood transfusion if no normal beta globin is produced. Mediterranean and caribbean people are more likely to have this disorder.

Hemoglobin sd, hemoglobin se, and hemoglobin so
These are the few rare and not less common types of sickle cell diseases. They are also less severe. People with these forms of scd inherit one sickle cell gene s and one gene from uncommon hemoglobin (d, e, or o) from each parent.

Sickle cell trait
Hbas
People with sct have one sickle cell gene s and one normal gene a from both mother and father. Ones with this disorder show few to no signs of the disease and usually spend a normal life. However, the risk to their future generations still exists.
 

What Are The Different Types Of Sickle Cell Disease?

Cushing syndrome occurs due to prolonged exposure to high levels of cortisol hormone. The condition, often referred to as hypercortisolism, affects women   usually between ages 25 and 40   more than men. Nearly 80% of adults and about 47% of children are diagnosed with cushing syndrome.

The most common cause of cushing syndrome is an overproduction of the stress hormone   cortisol   by the adrenal glands. However, it can also result from overuse of steroid drugs.

If you have cushing syndrome, you are likely to notice symptoms like muscle weakness, weight gain, a buffalo lump, irregular periods, sleep disorders, high blood glucose and high blood pressure.

Recent research has claimed to establish a relation between cushing syndrome and high blood pressure   or what is called hypertension in medical terms.

The link between hypertension and cushing syndrome

Hypertension refers to high blood pressure that causes the force of blood to raise against the artery walls. A number of conditions can lead to hypertension, such as poor diet and lifestyle, an underlying health issue, stress, pregnancy and so on.

As your body encounters stress, the adrenal glands produce and release cortisol in the bloodstream. Studies show that producing excess stress hormone can create a host of pathological problems in the body, including hypertension.

Hypertension is a distinguishing feature of endogenous cushing syndrome. High blood pressure in cushing syndrome has a significant correlation with the duration of hypercortisolism and results from the interaction between various pathophysiological methods regulating peripheral vascular resistance, cardiac output, and plasma volume   all of which are elevated in this state.

How to treat the condition

Cushing syndrome is usually treatable and curable. You will be prescribed to stop using steroid drugs that are likely to increase cortisol levels. If the condition does not improve after treatment, you will have to look for ways to manage the symptoms, especially by monitoring your blood pressure. Team up with your doctor and ask for ways to de-stress yourself.

Relation Between Cushing Syndrome And Hypertension: Know More

Potassium is one of the seven essential macrominerals found in a variety of foods, including legumes, fish, and leafy vegetables. The mineral plays a vital role in various body functions, such as regulating water balance, heart functioning, and muscle contractions.

Potassium deficiency can lead to weakness, ;fatigue, and constipation. It is therefore important that you include potassium-rich foods in your daily ;diet.

However, keep in mind that taking in more than the required amount of potassium can do more harm than good to your body.

How much should you take in and why?

As per the world health organization, the recommended daily intake of potassium for adults is between 3500mg and 4700mg, as it is safe to consume. When taken in recommended measures, a potassium-rich diet can have some impressive benefits on your overall health. It may reduce or prevent a host of health problems.


	
	Lower high blood pressure
	
	
	Helps eliminate salt insensitivity
	
	
	Reduces your chances of getting a ;stroke by 7%
	
	
	Helps prevent osteoporosis and minimizes the risk of bone fractures
	
	
	Alleviates the risk of ;kidney stones
	


Natural foods are the best source of this mineral. However, you may also turn to supplements, as per your healthcare provider s recommendation.

How much is too much?

Despite its health benefits, potassium should be consumed within the prescribed limit. Going overboard can cause excess potassium to be stored in your blood, and your kidneys may not be able to filter the excess amount   this condition could possibly lead to hyperkalemia. If your potassium levels are between 5.1mmol/l and 6.0mmol/l, you might be at risk of hyperkalemia. Higher than 6.0mmol/l level is considered dangerous   you will need to monitor and manage the condition in order to avoid the risk.

Potassium is essential for bodily functions. A healthy diet and overall eating patterns are important for maintaining good health and keeping illnesses at bay. Be sure to meet your recommended daily intake and avoid exceeding 4700mg of potassium daily. If you are looking to include supplements, talk to your doctor and make sure you stick to the prescribed dosage.

How Safe Is Potassium For Your Health?

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.
