- I choose this disease so I could learn more about it and I'm planning on becoming a nurse so I need to learn more about as many diseases as I can.

what is Hemophilia?

-A disorder in which your blood doesn't clot normally because it lacks sufficient blood clotting proteins. It's where if you get a deep cut you just keep bleeding for a longer period of time.

- it affects your whole body ( your blood and circulatory system)

- http://www.mayoclinic.org/diseases-conditions/hemophilia/basics/causes/con-20029824


- many large or deep bruises

-unusual bleeding after vaccinations

- blood in your urine or stool

-pain, sweeping or tightness in your joints

- nose bleeds without a known cause

- in infants , unexplained irritability

-neck pain

-repeating vomiting

-double vision

- extreme fatigue

-painful, prolonged headache



Inherited Disorder

-Hemophilia A or B: its located on the x chromosome, and its passed from mothers to sons. Mothers are usually carriers of the defective gene. Can't be passed from father to son.

-Hemophilia C: it can be passed from either parent to either boys or girls.

- "If the gene is faulty, the result is hemophilia, unless there is a dominant, normal gene on a matching x chromosome. Hemophilia is a recessive trait."



-Mild Hemophilia A: slow injection of the hormone desmorpressin (DDAVP) into a vein.

-Moderate to severe Hemophilia A or B: infusion of recombinant clotting factor or clotting factor derived from donated human blood.

-Hemophilia C: Clotting Factor XI , plasma infusions

-Clot- Preserving Medications (antifibrinolytics)

-Fibrin Sealants

-Physical Therapy

-First Aid for Minor Cuts




- A blood test can show a clotting factor deficiency in children and adults.

- In pregnancy testing can be done to determine if the baby has hemophilia but there's a high risk factor.

-one-third of babies who are diagnosed with hemophilia have a new mutation not present in other family members.

- If there's a family history then counseling can be an option.



Effects on the Population

-Hemophilia occurs in 1 in every 5,000 male births

- About 20,000 males in the US are living with this disorder

- It affects people from all racial and ethnic groups

- only males can receive it , females are the carriers

-Hemophilia A is about four times as common as hemophilia B, and about half of those affected have the severe form.

- About 400 babies are diagnosed with hemophilia each year


What I Discovered

-Hemophilia only happens in males ( females is rare to have it)

- Its rare

-Mothers are only carriers

- Its inherited

- Its treatable but not curable

-It affects all types of males
