A persistent feeling of a lump in the throat, known as globus, affects many people and can have various causes, from thyroid disorders to anxiety, according to health experts. While this sensation can be concerning, it is often not linked to a physical obstruction like food or a foreign object. Understanding the underlying causes can help individuals seek the appropriate medical care and relief.

Medical Conditions Linked to Globus

Globus is the sensation that something is stuck in the throat or chest, even when there is no physical obstruction. This feeling is often long-lasting and may prompt individuals to seek medical care. Some of the most common conditions associated with globus include thyroid disorders and gastroesophageal reflux disease (GERD).

According to a study, up to a third of people who report a sensation of something stuck in their throat are diagnosed with a thyroid disorder. This includes conditions such as hypothyroidism or hyperthyroidism, which can affect the muscles and nerves in the throat.

GERD occurs when stomach acid flows back into the esophagus, causing irritation and a feeling of something being stuck. This condition is often accompanied by heartburn or indigestion, and it can contribute to the sensation of globus even when no physical object is present.

Neurological and Psychological Factors

Nerve damage, such as injury to the recurrent laryngeal nerve or the vagus nerve, can also lead to globus symptoms. These nerves are responsible for controlling muscles in the throat and esophagus, and damage can result in altered sensation or discomfort.

Some studies suggest that neurological disorders, such as those affecting speech and swallowing, may be more common in individuals with conditions like diabetes. Neuropathies, which are complications of diabetes, can contribute to globus symptoms.

Psychological factors such as anxiety and stress are also linked to globus. Research indicates that people with globus tend to have higher stress levels and report more significant stressful life events. Stress can affect muscle tension in the esophagus, contributing to the sensation of a lump in the throat.

Globus associated with anxiety is more common in females between the ages of 36 and 45. In some cases, healthcare providers may consider psychological factors if no physical cause is identified.

Other Potential Causes and Diagnostic Procedures

Other potential causes of globus include inflammation of the upper airways, such as chronic sinusitis, postnasal drip, tonsillitis, and pharyngitis. These conditions can lead to irritation and the sensation of something being stuck in the throat.

In rare cases, injuries or degenerative changes in the bone structure of the neck, such as bone spurs in the cervical spine, can contribute to globus symptoms. Surgical procedures, including those for obstructive sleep apnea, may also lead to this sensation.

If a healthcare provider cannot find a physical cause for the symptoms, they may consider psychological factors. Diagnosis typically involves a thorough medical history, physical examination, and possibly an endoscopy. This procedure uses a flexible tube with a camera to examine the throat and esophagus, confirming the absence of any physical obstruction.

Other diagnostic tests may include imaging studies or blood tests to rule out conditions like thyroid disorders or neurological damage. In some cases, lifestyle changes, such as avoiding caffeine and spicy foods, may help alleviate symptoms.

Treatment for globus depends on the underlying cause. For GERD, medications such as proton pump inhibitors may be prescribed. For thyroid disorders, hormone replacement therapy or other treatments may be necessary. In cases of nerve damage, a combination of flupentixol and melitracen has been used to reduce the sensitivity of the vagus nerve.

If a person experiences persistent globus symptoms, it is important to consult a healthcare provider to determine the cause and develop an appropriate treatment plan. Globus can be uncomfortable, but it is often manageable with the right care and intervention.
