No, it cannot. It will end up in your mouth.
Yes, it can. The throat inflammation and burning of throat will cause large amounts of post nasal drip which could be the factor of sinus and nose pressure.
It can, but doesn't always.
Gastroesophageal reflux, which can lead to esophagitis or Barrett's esophagus.
Severe acid reflux can lead to esophagitis. The esophagus is the tube that carries food from the mouth to the stomach. Muscles in the lower esophagus normally prevent stomach acid from coming back up into the esophagus, but when a person suffers from mild, moderate or severe acid reflux, the muscles do not stop the acid from entering the esophagus and this stomach acid can cause pain and inflammation of the esophagus, which is caused esophagitis. Managing acid reflux disease is all about preventing acid from leaking back up into the esophagus.
Directly? No. Indirectly? Possibly. Chronic, untreated acid reflux can, in some cases, eventually lead to cancer of the esophagus - and that can kill you, yes.
Food breaks down more quickly and, in some cases, can lead to acid reflux.
Poor diet including hard to digest foods can lead to indigestion. Try drinking water and taking antacids. Laying down after a meal also may lead to a I'd reflux as the esophagus may not fully close.
A person may have severe sinus issues after running due to allergens in the air or a buildup of pressure. Running causes an increase in blood pressure which may lead to noticeable pain in the sinuses.
This is a disease that has the symptom of chronic inflammation of the sinuses. One of the complications of the disease is poor drainage, which can lead to sinus infections, pressure, and headaches.
High acidic foods are the best foods to avoid, such as tomatoes, citrus fruits and chocolate. Acid reflux is a terrible disease that causes the acid to rise from your stomach and can lead to esophageal problems if you do not maintain a healthy pH balance.
Personally, I think so. I have GERD (acid reflux disease) and if I don't get enough sleep, it will be much worse the next morning. I have discussed this with a GI dr and they say that many people with GERD do have worse symptoms if they do lack sleep.
The sinus infection itself might not even be an infection but could be the sign of a worse illness, so if the conditions that you think are a sinus infection dont go away you need to get it checked out as it could be due to pressure in the skull.
carbonic acid
If left untreated for a long period of time, the acid produced in severe cases of acid reflux (also known as GERD, or gastroesophageal reflux disease) can damage the soft tissue inside the throat and the esophagus.
