Final answer:
Adverse reactions to FEES can range from mild symptoms like dizziness, headache, and myalgia to severe cases leading to jaundice, rash, mucosal hemorrhaging, seizures, shock, and death.
Step-by-step explanation:
Possible adverse reactions to FEES (Flexible Endoscopic Evaluation of Swallowing) include several symptoms ranging from mild to severe. Mild reactions may include symptoms such as dizziness, headache, and myalgia (muscle pain). These symptoms are typically transient and resolve without requiring significant intervention. However, more moderate to severe reactions, although rare, can occur. These may include more concerning symptoms such as jaundice, where there is yellowing of the skin and eyes due to liver issues; rash and mucosal hemorrhaging, which is bleeding of the mucous membranes; and in very severe cases, there could be seizures, shock, and even death.
Like any medical procedure, there can be potential adverse reactions or side effects, although they are relatively rare. Some possible adverse reactions to FEES include dizziness, headache, and nausea. In moderate to severe cases, patients may experience more serious symptoms like seizures, shock, and even death.
