Medical Insights into Insomnia: Identifying Causes and Finding Effective Treatments

Insomnia is incredibly common, with acute or chronic insomnia impacting an estimated 1 in 3 adults. Stress, anxiety and bad sleep habits can all be culprits of poor sleep, but some medical issues are often overlooked as causes of sleepless nights. Conditions like sleep apnea, restless leg syndrome, gastrointestinal issues, chronic pain and hormonal imbalances can keep you up all night no matter how much time you spend in bed.

If you’ve been struggling with insomnia and think there’s an underlying medical cause, understanding these conditions and the treatments can be a big help. Let’s dive in to some of the medical causes of insomnia, the treatment options, and what to do if you’re still having trouble sleeping after you’ve addressed these.

1. Sleep Apnea

What is it:

Sleep apnea is a condition where your breathing stops and starts during sleep. These pauses in breathing can last from a few seconds to a minute and result in fragmented, poor quality sleep. There are two main types:

• Obstructive Sleep Apnea (OSA): Caused by a physical blockage in the airway, often due to the collapse of soft tissue in the throat.

• Central Sleep Apnea: When the brain doesn’t send the proper signals to the muscles that control breathing.

Symptoms:

• Loud snoring

• Gasping or choking during sleep

• Daytime fatigue or sleepiness

• Morning headaches

Treatments:

• CPAP (Continuous Positive Airway Pressure): A CPAP machine blows gentle air into your airway during sleep. Modern CPAP machines have come a long way—they’re quieter, more compact and have features like humidifiers and mask designs for comfort. Some even have smartphone apps to track your usage and provide feedback.

• Oral Appliances: For mild to moderate OSA an oral appliance fitted by a dentist can help by repositioning the jaw or tongue to keep the airway open. These are less cumbersome than CPAP and a good option for those who can’t adapt to a CPAP machine.

• Surgical Options: In severe cases surgery to remove excess tissue or reposition the jaw may be recommended.

• Lifestyle Changes: Weight loss, not drinking alcohol before bed and sleeping on your side can help.

For sleep apnea a consultation with a sleep medicine specialist is recommended. They’ll likely recommend a sleep study to confirm the diagnosis and determine the severity of the condition.

2. Restless Leg Syndrome (RLS)

What is it:

RLS is a neurological condition where you have an uncontrollable urge to move your legs, often with uncomfortable sensations like tingling, crawling or itching. Symptoms get worse at night making it hard to fall or stay asleep.

Treatments:

• Medications: Prescription drugs like dopamine agonists (e.g. pramipexole) or gabapentin can help. Iron supplements may also be recommended if low iron levels are contributing to RLS.

• Lifestyle Changes: Regular exercise, no caffeine and alcohol and a consistent sleep schedule can help manage symptoms.

• Home Remedies: Warm baths, leg massages or applying heat/cold packs to the legs before bed can help temporarily.

A general practitioner, neurologist or sleep medicine specialist can diagnose RLS and develop a treatment plan for you.

3. Gastrointestinal Issues

How they affect sleep:

Conditions like acid reflux, irritable bowel syndrome (IBS) or Crohn’s disease can cause discomfort that interferes with your sleep. For example, acid reflux gets worse when you lie down and can cause heartburn and disrupt your sleep.

Treatments:

• Acid Reflux: Over the counter antacids, proton pump inhibitors (PPIs) or H2 blockers can reduce stomach acid and symptoms. Elevating the head of your bed and not eating large meals or trigger foods before bed can also help.

• IBS or Crohn’s Disease: Managing these conditions often involves a combination of dietary changes, medications and stress management techniques.

A gastroenterologist can help you identify triggers and develop a treatment plan.

4. Chronic Pain

How pain affects sleep:

Pain from conditions like arthritis, fibromyalgia or migraines can make it hard to get comfortable and fall asleep. Even if you do fall asleep pain can cause frequent awakenings and prevent restorative sleep.

Treatments:

• Pain Management: Over the counter or prescription pain meds, physical therapy or nerve blocking treatments can help.

• Mind-Body Techniques: Mindfulness meditation, yoga and relaxation exercises can help reduce pain perception and improve sleep.

• Cognitive Behavioral Therapy for Pain (CBT-P): A therapist trained in CBT-P can help you develop strategies to cope with pain and sleep.

Pain specialists, rheumatologists or primary care physicians can work with you to manage chronic pain and sleep.

5. Hormonal Imbalances

Hormones and sleep:

Hormonal changes (especially in women) can disrupt sleep. Menopause, pregnancy and thyroid disorders are common culprits. For example, during menopause fluctuations in estrogen and progesterone can cause hot flashes, night sweats and insomnia.

Treatments:

• Hormone Replacement Therapy (HRT): For menopause related sleep issues HRT may help stabilize hormone levels and symptoms.

• Thyroid Treatment: If hypothyroidism or hyperthyroidism is affecting your sleep medications to regulate thyroid function can help.

• Lifestyle Changes: A cool and comfortable sleep environment and relaxation techniques can help minimize hormone related sleep disturbances.

An general practitioner, endocrinologist or gynecologist can help diagnose and treat hormonal imbalances that are causing insomnia.

When medical issues are ruled out: Therapy for insomnia

If you’ve addressed underlying medical conditions and still can’t sleep, therapy may be helpful.

is the treatment of choice for chronic insomnia. Unlike medications which often provide only short term relief for sleep issues, CBT-I addresses the thoughts and behaviors that keep sleep problems going.

CBT-I includes:

• Sleep restriction: Limiting the time in bed to match actual sleep time, gradually increasing it as you sleep better.

• Stimulus control: Strengthening the association between your bed and sleep by not doing wakeful activities like scrolling on your phone or watching TV in bed.

• Cognitive restructuring: Identifying and challenging negative sleep thoughts like “I’ll never fall asleep” or “I can’t function without 8 hours”.

A therapist trained in CBT-I can help you do these and tailor them to you.

Conclusion

Insomnia is a complicated condition with many causes including medical issues like sleep apnea, restless leg syndrome, gastrointestinal problems, chronic pain and hormonal imbalances. The good news is that each of these conditions has a treatment and that treatment can range from CPAP machines and medications to lifestyle changes and therapy.

If you’ve ruled out medical causes and still can’t sleep consider therapy for insomnia. With the right support and treatment plan better sleep is within reach, leading to better health, energy and quality of life. Reach out to a healthcare provider or therapist to get started tonight.
