Fatigue is more than just feeling tired; it’s a pervasive and debilitating exhaustion that significantly interferes with a person’s ability to function in their daily life. Individuals experiencing fatigue often describe an overwhelming lack of energy, making even simple tasks feel Herculean. This persistent tiredness isn’t relieved by rest and can manifest in a variety of physical, emotional, and cognitive symptoms. Understanding fatigue as a nursing diagnosis is crucial for providing effective patient care.
Causes of Fatigue
Fatigue is a complex symptom with a wide range of potential underlying causes. These can be broadly categorized into lifestyle factors, medical conditions, and medication-related factors. Identifying the root cause of fatigue is essential for developing an appropriate and effective care plan.
Lifestyle-Related Causes
Lifestyle choices play a significant role in energy levels and can contribute to fatigue. Common lifestyle-related causes include:
- Poor Diet: Inadequate nutrition, skipping meals, and diets lacking essential vitamins and minerals can lead to energy depletion and fatigue.
- Lack of Exercise: While it may seem counterintuitive, a sedentary lifestyle can actually worsen fatigue. Regular physical activity boosts energy levels and improves overall stamina.
- Excessive Alcohol Intake: Alcohol disrupts sleep patterns and can lead to dehydration, both of which contribute to fatigue.
- Substance Use: The use of illicit drugs can severely impact energy levels, often leading to chronic fatigue.
- Chronic Stress: Prolonged periods of stress deplete the body’s resources and can manifest as persistent fatigue.
Medical Causes
Numerous medical conditions can present with fatigue as a primary or secondary symptom. These conditions can range from acute infections to chronic diseases:
- Anemia: A deficiency in red blood cells or hemoglobin reduces oxygen delivery throughout the body, resulting in fatigue and weakness.
- Hypothyroidism: An underactive thyroid gland slows down metabolism, leading to fatigue, weight gain, and other symptoms.
- Diabetes: Both type 1 and type 2 diabetes can cause fatigue due to issues with blood sugar regulation and energy utilization.
- Heart Disease: Conditions affecting the heart’s ability to pump blood efficiently can lead to fatigue and shortness of breath.
- Chronic Kidney Disease: Kidney dysfunction can result in a buildup of toxins in the body, causing fatigue and weakness.
- Liver Disease: Similar to kidney disease, liver problems can lead to toxin accumulation and fatigue.
- Autoimmune Diseases: Conditions like lupus, rheumatoid arthritis, and multiple sclerosis are often associated with significant fatigue.
- Infections: Acute infections like influenza or mononucleosis, as well as chronic infections, can cause fatigue.
- Cancer: Cancer itself and cancer treatments, such as chemotherapy and radiation, are major causes of fatigue.
- Sleep Disorders: Conditions like insomnia, sleep apnea, and restless legs syndrome disrupt sleep quality and lead to daytime fatigue.
- Mental Health Conditions: Depression and anxiety disorders are frequently linked to fatigue and low energy.
Medication-Related Causes
Certain medications have fatigue as a common side effect. It’s important to consider medication lists when assessing the potential causes of fatigue. Common medication categories associated with fatigue include:
- Antidepressants: Some antidepressants, particularly tricyclic antidepressants and SSRIs, can cause drowsiness and fatigue.

Nursing Assessment for Fatigue
A comprehensive nursing assessment is the cornerstone of developing an effective care plan for fatigue. It involves gathering both subjective and objective data to understand the patient’s experience and identify contributing factors.
1. Assess Current Activity Level Compared to Baseline: Determine how fatigue is impacting the patient’s usual daily activities. Inquire about the onset, duration, and patterns of fatigue to understand its impact over time. This helps differentiate between acute and chronic fatigue and gauge the severity of functional impairment.
2. Assess Vital Signs: Monitor vital signs (temperature, heart rate, blood pressure, respiratory rate, oxygen saturation). Abnormalities like tachycardia, hypotension, or fever can indicate underlying physiological stress that contributes to fatigue. For example, tachycardia may suggest the heart is working harder to compensate for reduced oxygen-carrying capacity, while hypotension can indicate dehydration or cardiovascular issues.
3. Assess Lab Values: Review relevant laboratory results, such as complete blood count (CBC), thyroid function tests, blood glucose, electrolytes, and kidney and liver function tests. Abnormal values can point to underlying medical conditions causing fatigue. For instance, low hemoglobin levels in a CBC indicate anemia, while abnormal thyroid hormones suggest thyroid dysfunction.
4. Assess Full Medical and Surgical History: Obtain a detailed medical history, including past and present medical conditions, surgeries, and hospitalizations. Chronic conditions or recent medical procedures can significantly contribute to fatigue. Understanding the patient’s medical background helps identify potential medical causes of fatigue and tailor interventions accordingly.
5. Assess Imaging and Cardiac Studies: Review results of relevant imaging studies (e.g., X-rays, CT scans, MRIs) and cardiac studies (e.g., electrocardiogram, echocardiogram). These studies can reveal underlying structural or functional abnormalities that may be contributing to fatigue. For example, an echocardiogram can assess heart function and identify conditions like heart failure, which can cause fatigue.
6. Review Medication List: Thoroughly review the patient’s current medication list, including prescription drugs, over-the-counter medications, and supplements. Identify medications known to cause fatigue as a side effect. This allows for discussions with the provider about potential medication adjustments or alternatives.
7. Assess Need for Assistive Devices: Evaluate the patient’s need for assistive devices (e.g., walker, cane, wheelchair) to support mobility and activity. Assistive devices can help patients conserve energy and participate in activities with less fatigue.
8. Assess Psychological and Emotional Status: Evaluate the patient’s mental health, including mood, anxiety levels, and stress. Assess for symptoms of depression or anxiety, as these conditions are strongly linked to fatigue. Psychological factors can significantly influence the perception and experience of fatigue.
9. Assess Sleep Patterns: Inquire about the patient’s sleep habits, including sleep duration, sleep quality, sleep hygiene practices, and presence of sleep disturbances (e.g., insomnia, sleep apnea). Poor sleep is a major contributor to fatigue, and addressing sleep issues is crucial.
10. Assess Nutritional Status: Evaluate the patient’s dietary intake, eating habits, and nutritional status. Inquire about food preferences, dietary restrictions, and any recent changes in appetite or weight. Nutritional deficiencies can lead to fatigue, and dietary modifications may be necessary.
