Übelkeit

Übelkeit, often translated as nausea, is a subjective sensation of unease and discomfort in the upper abdomen, often accompanied by an urge to vomit. It is not a disease in itself but rather a symptom that can arise from a wide variety of causes. These causes can be broadly categorized into physiological, psychological, and environmental factors.

Physiological causes are very common. These include gastrointestinal issues such as food poisoning, infections, ulcers, or gastritis. Motion sickness, experienced during travel, is another well-known cause. Pregnancy, particularly in the early stages (morning sickness), frequently leads to nausea. Migraine headaches, certain medications (chemotherapy, opioids), and even overeating or consuming spoiled food can trigger this sensation. Hormonal imbalances and metabolic disorders can also be underlying factors.

Psychological influences play a significant role. Stress, anxiety, fear, and strong emotions can all manifest physically as nausea. A traumatic experience or exposure to unpleasant sights or smells can also induce it.

Environmental factors include exposure to toxins, strong odors, or certain airborne substances. In some cases, the exact cause of nausea may remain unclear, leading to the diagnosis of idiopathic nausea.

The experience of nausea can vary in intensity and duration. While it is often a precursor to vomiting, it can also occur independently. Treatment for nausea depends entirely on identifying and addressing the underlying cause. In many instances, nausea is a transient symptom that resolves on its own once the precipitating factor is removed or treated.
