Sleep Disorders: Understanding the Causes of Daytime Fatigue
Experiencing excessive fatigue during the day and struggling to stay awake may be indicative of various sleep disorders. These conditions can disrupt your sleep patterns and lead to inappropriate episodes of daytime sleepiness. Common sleep disorders include insomnia, characterized by difficulties in falling or staying asleep, and narcolepsy, which involves overwhelming feelings of tiredness during the day accompanied by sudden and uncontrollable sleep episodes.
It is worth noting that conditions preventing you from achieving a restful night’s sleep can also contribute to fatigue. For instance, sleep apnea manifests as abnormal breathing patterns while you sleep, while restless leg syndrome triggers an irresistible urge to move your legs as you attempt to drift off to sleep.
Medications and Treatments
There are several medications and treatments that can contribute to fatigue. Certain over-the-counter medications, such as allergy medications containing antihistamines, have been known to cause fatigue. Similarly, prescription medications used to manage conditions like high blood pressure, depression, seizures, anxiety, as well as pain medications and muscle relaxants, can also lead to fatigue. Fatigue is a prevalent side effect associated with chemotherapy and bone marrow transplants as well.
