Metallic Taste In Mouth After A Deep Cough

Having a salty or bad taste in your mouth is certainly not something to be brushed off, and if you are tasting blood while coughing, it is an alarming situation. Usually, the reason behind deep chest cough and consequent metallic taste is a respiratory infection. However, other factors can also contribute to this. Let’s discuss them in detail.

Metallic Taste in Mouth While Coughing – Causes

A bad or metallic taste in the mouth after a deep chest cough is common and not always a sign of a medical emergency. Here are the top 10 reasons why this may be happening:

  1. Common Cold or Upper Respiratory Infection
    An upper respiratory tract infection is mostly to blame for this. Consistent coughing up of phlegm may have some traces of blood in it that trigger the metallic taste.
  2. Sinus Infection
    You have sinus cavities present near your nose and an infection may lead to taste changes. When you have a deep chest cough due to inflammation and mucus you taste a bad metallic flavor.
  3. Exercise-induced Pulmonary Edema
    Yes, exercise is good for health but in moderation. Intense exercises can cause fluid buildup in your lungs leading to a metallic taste during a deep cough that sputes blood.
  4. Asthma
    For those with asthma or any other person who is new to intense exercise, wheezing or coughing sometimes occurs when breathing becomes difficult.
  5. Anaphylaxis
    When you are exposed to stimuli that trigger severe allergic reactions, your mouth alters its taste and can cause a metallic taste during a deep cough session. This is due to the release of histamine and other chemical mediators that irritate the respiratory tract.
  6. Gum disease
    Gum inflammation is common in this situation and leads to bleeding, which can contribute to taste deviation.
  7. Bronchitis
    It is one of the respiratory infections that causes intense mucus development in the lungs, which results in deep coughs and makes the mouth taste salty.
  8. Medications
    Certain medications, such as antibiotics, have direct drug-receptor interactions that produce a side effect of dysgeusia.
  9. Gastroesophageal reflux disease (GERD)
    Acid reflux causes a taste change due to the upward movement of stomach acid through the esophagus, irritating oral tissues and taste buds.

Deep Cough and Metallic Taste – Treatments

Treating the metallic taste when you have a cough pivots around finding out the root cause and resolving it. When it comes to colds or allergic coughs, over-the-counter (OTC) medications such as nasal decongestants, acetaminophen, and cough medicines can help.

Other routes include:

  1. Antibiotics
    They are a suitable choice for bacterial respiratory infections. Once the infection is gone, the cough should subside and the metallic taste with it. However, always remember that antibiotics only work on bacterial infections and not fungal or viral.
  2. PPIs (Proton Pump Inhibitors) and Lifestyle Modification
    Using proton pump inhibitors and managing a healthy lifestyle is key to dealing with GERD-related metallic tastes. Eating small but frequent meals, sleeping in an elevated position, and increasing physical activity to reduce gastric reflux.
  3. Antitussives
    Managing the cough with antitussives is a smart move when you are treating the underlying cause to deal with a metallic taste in the mouth.
  4. Cough Suppression Therapy
    Those who grapple with unexplained chronic coughs, physical and behavioral cough suppression therapy have shown benefits in easing the condition and associated symptoms.
