Besides lack of sleep, allergies and some serious underlying medical conditions can also cause dark circles. Another cause is head trauma, according to the health website Medical News Today (USA).
Dark circles under the eyes can be caused by lack of sleep or an underlying medical condition.
Dark circles around the eyes caused by injury or underlying disease are also known as panda eyes. The dark area around the eyes is due to broken blood vessels under the skin, leading to bruising. This condition is very different from dark circles caused by lack of sleep, which have nothing to do with blood vessel bleeding.
Dark circles under the eyes can be a sign of a serious health problem. If dark circles are accompanied by symptoms such as unusual lumps, dizziness, nausea, or discharge from the nose or ears, you should go to the hospital as soon as possible. The doctor will determine the underlying cause and intervene promptly.
If the cause of panda eyes is trauma, it's possible the victim suffered a traumatic brain injury. This occurs when the base of the skull is fractured, for example, due to a blow or impact in a traffic accident.
The skull base consists of the temporal bone, sphenoid bone, ethmoid bone, and occipital bone. Depending on the location and severity of the injury, one or more bones may be affected. Common symptoms of skull base fractures include dark circles under the eyes, headache, dizziness, and hearing loss.
Dark circles under the eyes can also be a sign of sinusitis, allergic inflammation, whooping cough, thrombocytopenia, and several other conditions. In rare cases, dark circles can also be a sign of neuroblastoma, a type of cancer that develops from nerve tissue in the neck, chest, abdomen, or pelvic area.
When treating dark circles under the eyes, doctors will order a CT scan or X-ray. For mild, non-life-threatening causes, dark circles usually resolve on their own within a few weeks without treatment. However, if there is a head injury, the patient needs urgent medical attention. Otherwise, complications such as brain hemorrhage or nerve damage may occur.
If the cause is a medical condition such as sinusitis or neuroblastoma, the doctor will use medication, surgery, chemotherapy, or a combination of other treatments depending on the situation, according to Medical News Today .
