What does it mean if you are coughing up B L O O D?

A couple of days ago, a really good friend of mine woke up and he was coughing up b l o o d. If it helps, he doesn't drink, smoke, or do . His parents took his to the hospitial and they couldn't find anything wrong with him, there was no b l o o d in his lungs or anything. They said that if it happens again then he should come back. This left me REALLY worried. What could be wrong with him? Is there nothing wrong at all, should I even be worried. My mom said that maybe he had broncitus or something, but he hasn't been sick or hoarse or anything. What do yall think could be wrong with him. I mean I find it a little fishy that a perfectly normal, healthy, teenage boy just start coughing up b l o o d out of the blue. Yall, please be respectful and no jokes just to get two points, this is my friend and I really care about him.

Obviusly im not going to tell you he needs a doctor because hes already had one ....there can be a number of reasons for this.

1) Bronchiectasis is an abnormal destruction and dilation (widening) of the large airways. A person may be born with it (congenital bronchiectasis) or may acquire it later in life as a result of another disorder.

2) Bronchitis is an inflammation of the main air passages to the lungs. Bronchitis may be short-lived (acute) or chronic, meaning that it lasts a long time and often recurs

3)Cystic fibrosis (CF) is caused by a defective gene which tells the body to produce abnormally thick and sticky fluid, called mucus. This mucus builds up in the breathing passages of the lungs and the pancreas, the organ that helps to break down and absorb food. This collection of sticky mucus results in life-threatening lung infections and serious digestion problems. The disease may also affect the sweat glands and a man's reproductive system.

4) Pneumonia is an inflammation of the lungs caused by an infection. Many different organisms can cause it, including bacteria, viruses, and fungi.

5) Pulmonary edema is usually caused by heart failure. As the heart fails, pressure in the vein going through the lungs starts to rise. As the pressure increases, fluid is pushed into the air spaces (alveoli). This fluid interrupts normal oxygen movement through the lungs, resulting in shortness of breath.
Pulmonary edema may be caused by damage directly to the lung, such as that caused by poisonous gas or severe infection. Lung damage and a build up of body fluid is also seen in kidney failure.

6) Pulmonary tuberculosis (TB) is a contagious bacterial infection caused by Mycobacterium tuberculosis (M. tuberculosis). The lungs are primarily involved, but the infection can spread to other organs.

Go to the emergency room and seek help quickly.

I would press to get most blood tests done. I know far fetched, but some diseases, such as Teburculosis, has syptoms that include coughing up blood.

Depends on how much blood. A minor sinus infection could cause you to cough up a small amount. If the hospital didn't find anything, there's no reason to worry right now.

Did the Doctor's do an endoscopy to look for bleeding ulcers in the stomach or duodenum? I'd recommend that he follow up with a family doctor or GI specialist.

The blood could be from pneumonia or a lung infection. Did the doctors do a chest x-ray?

Also, he should stay away from soda and spicy foods until he's better.

An ulcer?

If they didn't find anything in the lungs (like tuberculosis, etc..) then lets hope it's not a perforated stomach ulcer. Sometimes, if you are sick and vomiting, the thrust and the force can strain the inside and make you bleed, but if he's not been sick, then this sounds like a gastric problem to me. Is he taking any medications (aspirin, prednisone, etc?? He needs further evaluation if you ask me...bleeding is not normal.

Most likely an ulcer. I would go back th the er and demand some more tests

The coughing might be aggravating a small tear in the back of the throat. But it's depend on what the blood looks like...

If the hospital said there's nothing in the lungs or anything, then I doubt it's overly serious.

this may be this illness that you can get really sick from and if no treated something worse coul dhappen. i heard about it in this movie call moulon rouge with Nicole Kidman

Well, If you live in Texas I would insist on a test for pertussis(WHooping Cough) its going around big-time even if you have been immunized. The pertussis test takes a week for the culture to grow. My daughter had it and she coughed up blood and vomited. Also in Texas there has been several cases of tuberculosis. ER's usually don't want to take the time to run a full range of tests because they are busy. Go to doctor's office.
