What is HHT?
It stands for hereditary hemorrhagic telangiectasia. It's a disorder that results in the development of multiple abnormalities in the blood vessels. In future if you have questions like that you could google them.

Recurrent nosebleeds are a nearly universal symptom in this condition. Usually the nosebleeds begin in childhood and become worse with age.
What is the treatment for hereditary hemorrhagic telangiectasia?
by applying compresses or direct pressure to the area. If necessary, a laser can be used to destroy the vessel. In severe cases, the leaking artery can be plugged or covered with a graft from normal tissue.
What are the signs and symptoms of hereditary hemorrhagic telangiectasia?
as small, red or reddish-violet spots on the face, lips, inside the mouth and nose or the tips of the fingers and toes. Other small telangiectasias may occur in the digestive tract.
Is High Blood Pressure one of the Symptoms of Hereditary Hemorrhagic Telangiectasia?
no i don't think so. i have it and i have tried to learn a lot about it and while high blood pressure may be something you have to deal with along side the HHT i am pretty sure it is not an actual symptom of the disease

no
How is ataxia-telangiectasia diagnosed?
Diagnosis relies on recognizing the hallmarks of A-T: progressive ataxia and telangiectasia. However, this may be difficult as ataxia symptoms do appear prior to telangiectasia symptoms by several years
What is ataxia-telangiectasia?
Ataxia-telangiectasia (A-T) is a rare, genetic neurological disorder that progressively affects various systems in the body.
Osler-Weber-Rendu syndrome?
DefinitionOsler-Weber-Rendu syndrome is an inherited disorder of the blood vessels that can cause excessive bleeding.Alternative NamesHereditary hemorrhagic telangiectasia; HHTCauses, incidence, and risk factorsOsler-Weber-Rendu syndrome is an inherited condition. It can affect males or females of any ethnic or racial group.People with this condition can develop abnormal blood vessels called arteriovenous malformations (AVMs) in several areas of the body. If they are on the skin, they are called telangiectasias. The AVMs can also develop in other areas of the body, such as the brain, lungs, liver, or intestines.The syndrome is genetic, which means it results from an abnormality in one of a few genes. Scientists have identified some of the genes involved. However, they do not know exactly how the gene defects lead to the abnormal blood vessels seen in persons with this syndrome.SymptomsFrequent nosebleeds in childrenGI bleeding, including loss of blood in the stool or dark black stoolsPort wine stainSeizures or unexplained, small strokes (from bleeding into the brain)Shortness of breathTelangiectases on the tongue, lips, nasal mucosa, face, ears, fingertips, nails, whites of the eyes, and skin (they may bleed easily)Signs and testsAn experienced health care provider can detect telangiectases during a physical examination. There is often a family history of hereditary hemorrhagic telangiectasia.Signs include:Abnormal blood vessels that bleed easily in the throat, bowels, or airwaysAVM seen on chest x-rayDecreased oxygen levels in the bloodHeart failureHepatomegalyIron deficiency anemiaTests include:Blood gas testsBlood testsEchocardiogramEndoscopyGenetic testing may be available for changes (mutations) in the endoglin or ALK1 genes.TreatmentTreatments include:Surgery to treat bleeding in some areasElectrocauteryor laser surgery to treat frequent or heavy nosebleedsEndovascular embolization to treat abnormal blood vessels in the brain and other parts of the bodySome patients respond to estrogen therapy, which can reduce bleeding episodes. Avoid taking blood-thinning medications.Some patients may need to take antibiotics before having dental work or surgery. Ask your doctor what precautions you should take.Support GroupsHHT Foundation International -- www.hht.orgExpectations (prognosis)People with this syndrome can live a completely normal lifespan, depending on the parts of the body where the AVMs are located.ComplicationsHeart failureHigh blood pressure in the lungs (pulmonary hypertension)Internal bleedingShortness of breathCalling your health care providerCall your health care provider if your child has frequent nose bleeds or other signs of this disease.PreventionGenetic counseling is recommended for couples who want to have children and who have a family history of hereditary hemorrhagic telangiectasia. Medical treatments can prevent certain types of strokes and heart failure.ReferencesAzuma H: Genetic and molecular pathogenesis of hereditary hemorrhagic telangiectasia.
