Fatigue Causes – What’s Draining Your Energy?

When talking about fatigue causes, the various biological, lifestyle, and environmental factors that make you feel constantly tired. Also known as tiredness reasons, this concept pulls together several key players. One big player is medication side effects, unwanted reactions from drugs that can sap energy (sometimes called drug adverse effects). Another is dehydration, a state where the body lacks enough fluid to keep cells working efficiently (also referred to as fluid loss). Inflammation, the body’s immune response that can become chronic and wear you down (known as body inflammation) also plays a role. Finally, stress, the mental and physical pressure that spikes cortisol and disrupts sleep (sometimes called psychological stress) often intensifies the feeling of fatigue. In short, fatigue causes encompass medication side effects, dehydration, inflammation, and stress, each influencing the others in a feedback loop.

Typical Triggers and How They Interact

Let’s break down how these triggers show up in everyday life. First, many prescription drugs—like anticoagulants, muscle relaxants, or antidepressants—list tiredness as a common side effect. If you’ve started a new medication and notice sluggishness, that could be the drug’s impact on your nervous system or blood flow. Next, dehydration is sneaky; even a mild fluid deficit can lower blood pressure, reduce oxygen delivery, and make you feel drained. Simple habits like skipping water with coffee or sweating a lot without replenishing fluids set the stage. Chronic inflammation, whether from an autoimmune condition, persistent infection, or an unhealthy diet, releases cytokines that meddle with energy metabolism, leaving you fatigued even after a full night’s sleep. Stress adds the final piece: high cortisol levels interfere with the body’s natural sleep‑wake cycle and can amplify both inflammation and dehydration by prompting poor eating and drinking habits. Recognizing which of these you’re dealing with—sometimes more than one at once—helps you target the right fix.
