What are the Major Types of Anaemia ?

-
Anaemia is the common disorder in all ages of the population. It is caused by decreased production of red blood cells in the body. Anaemia is often a by-product of other diseases which either interfere with the body's ability to produce healthy RBCs or abnormally increase red blood cell destruction or loss. In this blog, we will discuss various types of anaemia and their causes.

Iron deficiency anaemia
The iron deficiency anaemia is the most common type worldwide. It is caused by a shortage of iron molecules in your body. Your bone marrow needs iron to make haemoglobin. Without the adequate amount of iron, your body can't produce sufficient haemoglobin for red blood cells. Without iron supplementation, this type of anaemia occurs in usually in pregnant women. There are many other reasons where this anaemia is caused by blood loss, such as from an ulcer, cancer, heavy menstrual bleeding, and regular use of some over-the-counter pain relievers, especially aspirin.

Vitamin deficiency anaemia
In addition to iron, your body also requires vitamin B12 and folate to produce ample amount of healthy RBCs. If your diet lacks these ingredients, it affects the formation of RBCs in the body. Additionally, some people may consume adequate vitamin B-12, but their bodies aren't able to process the vitamin. This can lead to vitamin deficiency anaemia, also known as pernicious anaemia. You can either include the required nutrients in your food or buy the required vitamins and supplements from trusted pharmaceutical wholesalers in the UK.

Anaemia of chronic disease
Certain diseases, such as HIV/AIDS, cancer, rheumatoid arthritis, Crohn's disease, kidney disease and other chronic inflammatory diseases can interfere with the production of red blood cells.

Aplastic anaemia
This rare, life-threatening anaemia occurs when your body doesn't produce enough red blood cells. Causes of aplastic anaemia include infections, autoimmune diseases, certain medicinesand exposure to toxic chemicals.

Anaemias associated with bone marrow disease
A variety of diseases, such as leukaemia and myelofibrosis can, affect the production of RBCs and can cause anaemia. Bone cancer can damage bone marrow tissue and the body’s ability to manufacture red blood cells, thereby causing anaemia.

Haemolytic anaemias
This group of anaemias develops when red blood cells are destroyed quickly than bone marrow can replace them in time. Certain blood diseases raise red blood cell destruction. You can inherit a haemolytic anaemia, or you can develop it later in life.

Sickle cell anaemia
This inherited, and a sometimes serious condition is an inherited haemolytic anaemia. It's caused by a defective form of haemoglobin that forces RBCs to assume an abnormal sickle shape. These irregular cells die prematurely, resulting in a chronic shortage of RBCs.

Uses of Defibrillator and the Help It Renders In Attending a Patient

-
Image
A defibrillator is a medical technique which is used to prevent ventricular fibrillation which is a common cause of cardiac arrest. The use of defibrillator is quite easy. However, due to the lack of knowledge many people use it in the wrong way. Here are the things you should check before using it. If you find someone having difficulty in breathing or choking due to the inability to breathe, calling the emergency number is the call of time. Other than that, you can start the CPR to keep a continuous supply of blood within the body. On the contrary, without CPR, the chance of death increases for the person. In case you're without anyone else, don't stop the CPR to go and get a defibrillator. In case it is not available, send another person to find the same for you. When you call 999, the administrator can let you know whether there's a community defibrillator close-by. When you open the equipment as provided by the defibri...

Why is antimalarial prophylaxis important?

-
Image
Every year, around 300–500 million people contract malaria and about 3 million die, most of which are children who are under five years. In sheer numbers, malaria kills 3,000 children per day under the age of five. The total number of deaths readily exceeds that from AIDS. After Tuberculosis, Malaria is easily the world's largest parasitic disease, killing more and more people every day. As we know, Malaria is one of the oldest pathogens which is posing a threat to the human population since the birth of the agriculture. Antimalarial prophylaxis Even being such a potent disease on the face of the earth, there is no post-disease vaccine available for protection against malaria despite the decades of research. Antimalarial prophylaxis is one of the newly surfaced modes of protection against the Malaria which offers an alternative approach that provides reliable protection against malaria. Antimalarial prophylaxis offers protection against clinical attacks of malaria especi...

Malaria - a rising global threat

Despite its small size, the mosquito is the most dangerous animal to have caused maximum human deaths. According to the most recent estimates from World Health Organization, about 50% of the world’s population is at risk of Malaria. In the year 2015, 215 million cases of malaria registered of which resulted in 4,38,000 deaths. What is Malaria? Malaria is an infection caused in Red Blood cells (RBCs) by a parasite called Plasmodium.  Plasmodium falciparum is the most potent parasite reported to have cause Malaria. Other less known species that cause Malaria are Plasmodium vivax, Plasmodium ovale, Plasmodium malariae, Plasmodium knowlesi. Once the parasites enter your body, they mature in the liver. These mature parasites later infect the RBCs.  Commonly known symptoms of Malaria are malaise,  vomiting, and fever with chills.  Unavailability of treatment can worsen the symptoms and cause anaemia, hypoglycemia and Cerebral Malaria (obstructs supply of bloo...
