Immediate attention of a doctor is necessary if the condition lasts for more than a week or if the blood is more than a few teaspoons. Seeking doctor's attention is also sensible if the condition is accompanied by other symptoms, such as chest pain, dizziness, weight loss, excessive sweating in the night, fever and breath shortness, as stated by the National Institutes of Health's MedlinePlus.
Medically referred to as hemoptysis, coughing up blood can be a symptom of a serious medical issue. It can be an indication of cancer, problems in the lungs or blood vessels and certain infections. If spitting up blood is not caused by bronchitis, seeking medical attention for an examination is necessary. There are several potential causes of splitting up blood, including crack cocaine, tuberculosis, pneumonia, pulmonary embolism, cystic fibrosis, congestive heart failure and bronchitis among others. This condition can also be caused by bleeding outside the airways and the lungs, as stated by WebMD.
people may experience unexplainable hemoptysis, but it tends to clear up after six months. The doctor may carry out a test to figure out the rate of bleeding and any problem that may affect breathing. Such tests include X-ray, bronchoscopy, physical examination, lung scan, CT scan and complete blood count among others.
