Blood donation is a procedure carried out for the noble cause of helping patients and saving lives. As the healthy donor's blood is transfused into the patient, it gives them a new life. That said, the donor has to fulfill a few criteria to be eligible to donate blood.

Eligibility

While any healthy adult of any gender can donate blood, it is advised for males to donate once every three months and for females to donate once every four months. Some of the other criteria are-


	
	Age
	


Any person in the age group of 18 to 65 years can donate blood depending on other factors.


	
	Weight
	


A donor should be at least weigh 45 kilograms in order to be eligible.


	
	Pulse
	


The temperature and pulse of the donor should be normal during the time of blood donation.

Know Eligibility Rules For Donating Blood

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.

Surprising benefits of donating blood

Blood is that element in the human body that can't be manufactured. Hence, it makes blood donation a very significant phenomenon. It benefits the patients, the donors, society, and the overall medical ecosystem. However, people are not particularly aware of some of the benefits of donating blood. While some of them are necessarily good for your overall health, some can even surprise you.

Benefits

Potentially reveal health issues
Donating blood gets your vitals checked to make sure you are adequately fit for the procedure. Hence, it can be a process to keep your overall health checked. Your pulse, blood pressure, and hemoglobin check can ensure that you are free of any chronic illness. Usually, blood low in iron is not taken for donation. As a result, blood donation can find health issues that can be eradicated from the roots.

Reduce harmful overload of iron
Iron overload in the body causes a condition called hemochromatosis. Although this condition is not a usual phenomenon in india, it is important to detect it at the earliest. Blood donations help eliminate the excess iron from the body through red blood cells.

Cardio and vascular health
Regular blood donation maintains low blood pressure and keeps the risk of heart attacks at bay. According to a study, donating blood reduces the chance of heart attacks by 88 percent. High hemoglobin and high iron stores are checked by blood donations that have to do with blood clots and strokes.

Reduce the risk of cancer
A high concentration of iron in the body can cause free-radical damage. It increases the risk of cancer in the lungs, liver, colon, and throat due to the lowering of oxidative stress. Thus, regular blood donations make sure that the risk of cancer and mortality is lower.

Liver stays healthy
Excess iron in the body gets stored in the liver, heart, and pancreas leading to a risk of cirrhosis or liver failure. Various health ailments related to the liver are prevented by donating blood and getting rid of the extra iron in the body.

Help your mental state
With several physical benefits, there are also some psychological edges. As donating blood directly or indirectly helps a patient, it gives a sense of pride and satisfaction. Making a difference in society feels extremely fulfilling and that keeps you in an elated state. Hence, blood donation is equally healthy for your body and mind.

Surprising Benefits Of Donating Blood

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?

Type 1 diabetes occurs when your pancreas is unable to produce enough insulin to keep the blood sugar ;levels under control. The condition, if not managed properly, can lead to related health disorders and complications, both long-term and short-term.

Health problems arising from type 1 diabetes

Type 1 diabetes can have severe effects on your eyes, kidney, nervous system, and heart health. The most common ailments associated with type 1 diabetes may include the following-

1. Diabetic retinopathy

Diabetic retinopathy is a disease of the eyes, which occurs when the blood vessels in the retina (tissue present at the back of your eyes) are damaged. The walls of the retina gradually weaken from increasing blood pressure and blood sugar levels, and this leads to leakage of blood or fluid into the nearby tissues.

Early symptoms of diabetic retinopathy include-


	
	Blurred vision
	
	
	Floaters
	
	
	Difficulty perceiving colors
	


2. ;Diabetic neuropathy

Diabetic neuropathy unfolds when the nerves are damaged due to type 1 diabetes. The condition mostly affects your feet and legs. Reduced blood circulation due to high blood glucose impedes normal wound healing in the extremities, hence, even a minor bruise ;can develop into a permanent injury.

Symptoms of diabetic neuropathy are-


	
	Numbness
	
	
	Reduced sensation
	
	
	Severe, debilitating pain in the extremities
	


3. Diabetic nephropathy

Also known as ;diabetic kidney disease, the condition is a slow deterioration of the kidney and its ability to function properly. In severe cases, where the levels of blood glucose are extremely high due to type 1 diabetes, diabetic nephropathy can ultimately result in kidney failure ;or end-stage renal disease (esrd).

The following are the symptoms of diabetic nephropathy-


	
	Dark urine
	
	
	Swollen ankles, feet, eyes, or hands
	
	
	Shortness of breath
	


4. Cardiovascular diseases

Cardiovascular diseases refer to a range of heart conditions including blood clots and diseased blood vessels. High blood glucose levels resulting from type 1 diabetes can contribute to the deposition of fat in the walls of the blood vessel. Over time, this may restrict the flow of blood and put you at risk of cardiovascular disorders such as coronary artery disease, stroke, or even ;heart attack.

Symptoms of cardiovascular diseases widely vary, ranging from palpitations ;to chest pain. Sometimes, such a condition may not exhibit any symptoms at all.

Type 1 diabetes complications are related to poor management of blood glucose. The best way to monitor the condition and control the symptoms is to get in touch with your doctor. A specialist in this field can prescribe the correct treatment and help prevent the onset the related health disorders.

Complications Associated With Type 1 Diabetes

The most common forms of diabetes ;are type 1 and type 2 diabetes. In type 1, your immune system damages the cells inside the pancreas that produce insulin. Therefore, the pancreas are unable to produce an adequate amount of insulin.

In type 2 diabetes, your body does not respond properly to the insulin produced by the pancreas. As a result, your body will have a difficult time removing sugar ;from the blood. The cells may stop insulin production over time that may lead to insulin deficiency. However, there are other forms of diabetes that are lesser-known but can affect you just as bad.

Types of diabetes beyond type 1 and type 2

Gestational diabetes

In gestation diabetes, a condition that affects pregnant women, the blood sugar levels increase to an extent that may hamper the health of the mother and the child.

Symptoms

Usually, there are no symptoms as such. If diabetes worsens, women may observe symptoms such as -


	
	A need to pee more frequently
	
	
	Excessive thirst and hunger
	
	
	Dryness in the mouth
	


Lada (latent autoimmune diabetes in adults)

It is sometimes referred to as type 1.5 diabetes. Here, your immune system kills the insulin-producing cells inside the pancreas. As this condition takes a longer period to develop, you may not need insulin for many months after you have been diagnosed.

Symptoms

You may observe the following symptoms  


	
	Dryness and itchiness
	
	
	Tingling sensation in feet or hands
	
	
	Blurry vision
	
	
	Frequent urination
	


Mody (maturity-onset diabetes of the young)

This condition is observed during adolescence. Here, genetic mutations limit the pancreas from making insulin. So, due to insufficient insulin, your blood sugar level goes up. If any of your parents have mody, you are likely to have the condition.

Symptoms

Symptoms may include  


	
	Yeast and ;skin infections
	
	
	Frequent urination
	
	
	An urge to pee more often
	


Treatment

Primary care for these other forms of diabetes follows the usual course of treatment as with type 1 and type 2.


	
	Diabetic medications
	
	
	Insulin shots or injections
	
	
	Dietary changes
	


The doctor may instruct you to monitor your blood sugar levels frequently to keep it under control. This will be accompanied by a diet ;consisting of adequate calories, but avoid fatty foods, excess sugar and carbohydrates. Mild exercise is also recommended.

The best way to prevent these conditions is to visit your doctor frequently and follow the treatment plan. Do not keep your diabetes untreated.
