The exact mechanisms behind exercise hyperpnea are not well understood, and some hypotheses are somewhat controversial. However, in addition to low oxygen, high carbon dioxide, and low pH levels, there appears to be a complex interplay of factors related to the nervous system and the respiratory centers of the brain that governs hyperpnea.

In the case of the second cause, the sensation of obstruction is subjective. Bleeding from the nose, also called epistaxis, may occur when the dried discharge (crusts) are removed. Septal perforation and dermatitis of nasal vestibule can occur. The nose may show a saddle-nose deformity.
Epistaxis (blood coming from one or both nostrils) is much less common, occurring in 0.25–13% of cases. [1] [9] In a survey of over 220,000 horse starts in UK Flat and National Hunt (jump) racing, 185 cases of epistaxis were identified (0.83 per 1000 starts). Similar frequencies have been reported in Japan (1.5 per 1000 starts) and South ...
A nosebleed, also known as epistaxis, is an instance of bleeding from the nose. [1] Blood can flow down into the stomach, and cause nausea and vomiting. [8] In more severe cases, blood may come out of both nostrils. [9] Rarely, bleeding may be so significant that low blood pressure occurs. [1]
A history of exposure to potential causes and evaluation of symptoms may help in revealing the cause the exacerbation, which helps in choosing the best treatment. A sputum culture can specify which strain is causing a bacterial AECB. [5] An early morning sample is preferred. [7] E-nose showed the ability to smell the cause of the exacerbation. [8]
The CDC report analyzed data from laboratory-confirmed flu-related hospitalizations in children and adults between 2010 and 2023. It noticed a few trends in risk factors for severe flu. Those include:
Some other examples include lung diseases such as pneumonia, metabolic disorders such as hypocalcemia, kidney diseases like renal cell carcinoma, and hiccups can also be a symptom of tumors in the ...
But my mom, who is a nurse, noticed that my white blood cell count was concerningly high, which could be a sign of infection or a bone marrow disease. This felt like a red flag, especially because ...
