EVALI (E-cigarette or Vaping product use-Associated Lung Injury) is a serious lung condition that has been linked to vaping products. First identified in 2019, EVALI can cause severe respiratory symptoms and requires immediate medical attention. Understanding the common symptoms associated with this condition is important for anyone who uses vaping products or is concerned about potential exposure. This article outlines the key symptoms that have been reported in EVALI cases, helping you recognize when medical evaluation may be necessary.
1. Persistent Cough
A persistent, dry cough is one of the most frequently reported symptoms in EVALI cases. This cough typically develops gradually and may worsen over time. Unlike a typical cold or seasonal cough, the cough associated with EVALI tends to be more severe and doesn’t improve with standard over-the-counter cough medications.
The cough may be accompanied by a feeling of chest tightness and can interfere with daily activities and sleep. Some individuals report that the cough is particularly bothersome at night or when lying down. If you experience a persistent cough that doesn’t resolve within a few days, especially if you have a history of vaping, it’s important to consult with a healthcare provider for proper evaluation.
2. Shortness of Breath
Shortness of breath, also known as dyspnea, is another common symptom reported in EVALI cases. This symptom typically manifests as difficulty breathing or feeling like you can’t get enough air. The shortness of breath may occur during physical activity initially but can progress to affect breathing even at rest.
Individuals with EVALI-related shortness of breath often describe feeling winded after minimal exertion or having to work harder to breathe normally. This symptom can be particularly concerning because it can significantly impact quality of life and may indicate serious lung inflammation. If you experience unexplained shortness of breath, especially with a history of vaping, seek medical attention promptly.
3. Chest Pain
Chest pain is frequently reported among individuals with EVALI and can vary in intensity and location. The pain may be described as sharp, stabbing, or a dull ache that persists in the chest area. Some people report pain that worsens with deep breathing or coughing.
The chest pain associated with EVALI is often related to inflammation in the lung tissue and surrounding structures. It may be accompanied by a feeling of pressure or tightness in the chest. This type of pain should not be ignored, as it can indicate significant lung injury that requires medical evaluation and treatment.
4. Fever and Chills
Fever and chills are systemic symptoms that commonly occur in EVALI cases. The fever may be mild to moderate, typically ranging from 100°F to 102°F (37.8°C to 38.9°C), though it can sometimes be higher. Chills often accompany the fever and may come and go throughout the day.
These symptoms indicate that the body’s immune system is responding to the lung injury and inflammation. The fever and chills may be accompanied by general feelings of malaise and fatigue. If you develop a fever along with respiratory symptoms and have a history of vaping, it’s important to seek medical care for proper evaluation and treatment.
5. Fatigue and Weakness
Extreme fatigue and weakness are common symptoms experienced by individuals with EVALI. This fatigue goes beyond normal tiredness and can be debilitating, affecting the ability to perform routine daily activities. The weakness may be generalized throughout the body and can persist even with adequate rest.
This symptom is often related to the body’s response to lung inflammation and reduced oxygen levels in the blood. The fatigue may be accompanied by a general feeling of being unwell or “run down.” If you experience persistent, unexplained fatigue along with respiratory symptoms, especially with a history of vaping, medical evaluation is recommended.

6. Nausea and Vomiting
Gastrointestinal symptoms, including nausea and vomiting, have been reported in many EVALI cases. These symptoms may occur alongside respiratory symptoms and can contribute to overall discomfort and illness. The nausea may be persistent and can interfere with eating and maintaining proper nutrition.
Vomiting, when it occurs, may be intermittent and can lead to dehydration if not properly managed. These gastrointestinal symptoms are thought to be related to the systemic inflammatory response that occurs with EVALI. If you experience persistent nausea or vomiting along with respiratory symptoms, it’s important to seek medical attention for proper evaluation and supportive care.
7. Diarrhea
Diarrhea is another gastrointestinal symptom that has been reported in EVALI cases. This symptom may occur independently or alongside other gastrointestinal symptoms like nausea and vomiting. The diarrhea can range from mild to severe and may contribute to dehydration if not properly managed.
Like other gastrointestinal symptoms associated with EVALI, diarrhea is believed to be part of the body’s systemic response to lung injury and inflammation. This symptom can be particularly concerning when combined with respiratory symptoms, as it may indicate a more severe case of EVALI that requires immediate medical attention.
8. Weight Loss
Unintentional weight loss has been observed in some EVALI cases, particularly in more severe or prolonged cases. This weight loss may occur due to a combination of factors, including decreased appetite, nausea, vomiting, and the body’s increased energy expenditure in fighting the illness.
The weight loss associated with EVALI is typically noticeable and occurs over a relatively short period. It may be accompanied by a general feeling of weakness and fatigue. If you experience unexplained weight loss along with respiratory or gastrointestinal symptoms, especially with a history of vaping, it’s important to seek medical evaluation promptly.

Conclusion
EVALI is a serious condition that can cause a range of symptoms affecting the respiratory system and other parts of the body. The symptoms described above represent the most commonly reported signs associated with this condition. It’s important to note that symptoms can vary between individuals and may develop gradually or appear suddenly.
If you use vaping products and experience any combination of these symptoms, especially respiratory symptoms like persistent cough, shortness of breath, or chest pain, it’s crucial to seek medical attention promptly. Early recognition and treatment of EVALI can help prevent serious complications and improve outcomes. Healthcare providers can perform appropriate tests to evaluate lung function and determine the best course of treatment.
