Agranulocytosis is a condition characterized by reduced number of Granulocytes. Granulocytes are a type of white blood cells that are responsible for healthy immunity. Granulocytes are filled with microscopic granules that contain enzymes which digest microorganisms. Granulocytes are made in bone marrow and it travels the whole body through blood. When the numbers of granulocytes are drastically reduced within the body, leaving them too few in numbers, the resulting condition is called ‘Agranulocytosis’.

Alternate names

Granulocytopenia, Granulopenia


Since Agranulocytosis is a condition where immunity decreases, the possibility of an infection to occur increases dramatically. The symptoms of Agranulocytosis are usually the symptoms of infection. However, in absence of any infection, Agranulocytosis can be asymptomatic.

  • Treatment of Agranulocytosis depends on the cause. For example, if a drug/medicine is causing it, discontinuation of the drug is required. Shifting patient on a nutrition rich diet if the cause is poor nutrition may help. Discontinuation of the drug that causes bone marrow depression may help.
  • In severe cases of Agranulocytosis, transfusion of granulocytes can also be considered.

In today's fast paced life, we often come across minor health issues that we often neglect due to lack of time for paying a visit to a doctor, which usually takes away 2-3 hours of a person's time and are expensive too. Further more, such minor conditions may grow big at any time if neglected. Our aim in setting up this platform is that any person can search for any health condition or medicines and can get all the needed information within hardly 10-15 minutes, which saves a lot of time and money. After going through every information, if the person has any questions, he/she can go to our forums section and raise a topic. This will help him/her decide better whether he/she needs to pay an immediate visit to a doctor or can it wait for a day or two? Help us in bringing awareness about diseases and medicines by spreading the word to at least 5 of your friends and relatives.
