Malaise: Causes, Symptoms, and When to Seek Medical Care

Malaise is a medical term used to describe a general feeling of discomfort, weakness, or not feeling well, often without a clearly identifiable cause. People experiencing malaise may feel as though they are “coming down with something,” yet rest does not restore their sense of well-being.

Malaise can develop suddenly or gradually and may last for days or even weeks. In Canada, malaise is a common reason individuals seek medical advice or present concerns during first aid assessments, as it often accompanies infections, chronic illness, or systemic stress on the body.

Possible Causes of Malaise

Malaise is not a condition on its own—it is a symptom that can arise when the body is responding to illness, injury, or physiological stress.

Medical Conditions

Many acute and chronic conditions can trigger malaise. A healthcare professional should be consulted to determine the underlying cause.

Musculoskeletal disorders frequently cause a persistent sense of discomfort and unease. Malaise is commonly reported among individuals with joint conditions such as rheumatoid arthritis and osteoarthritis.

Acute and systemic illnesses that may cause malaise include:

• Lyme disease

• Fibromyalgia

• Hepatitis

• HIV/AIDS

Chronic health conditions associated with malaise include:

• Kidney disease

• Severe anemia

• Diabetes

• Congestive heart failure

• Chronic obstructive pulmonary disease (COPD)

• Liver disease

Medications

Certain medications may contribute to feelings of malaise, including:

• Antihistamines

• Anticonvulsants

• Some psychiatric medications

• Medications used to manage high blood pressure and heart disease

When to See a Doctor

Medical advice should be sought if:

• Malaise lasts longer than 7 days

• The feeling becomes overwhelming or interferes with daily activities

• Malaise is accompanied by symptoms such as fever, pain, weight loss, shortness of breath, or dizziness

A healthcare provider can determine whether further testing is required and recommend appropriate treatment.

Managing Malaise

Because malaise has many possible causes, treatment focuses on addressing the underlying condition rather than the symptom itself.

General strategies that may help reduce malaise include:

• Getting adequate rest

• Reducing physical and emotional stress

• Engaging in light, regular physical activity as tolerated

• Maintaining a balanced, nutritious diet

Tracking symptoms can be helpful. Keeping a simple journal of physical symptoms, energy levels, and daily activities may assist healthcare providers in identifying patterns or triggers.
