Insomnia is a common sleep disorder in which a person has trouble falling asleep, staying asleep, or getting good quality sleep even when there is enough time and a suitable place to rest. Short-term insomnia lasts a few days or weeks and often follows stress or a schedule change, while chronic insomnia happens at least three nights a week for three months or longer. Poor sleep affects mood, focus, and overall health. Avita MD primary care providers diagnose and manage insomnia for adults in Los Altos, Mountain View, and Los Gatos.

What are the symptoms of insomnia?

Insomnia shows up at night and during the day. Common signs include:

  • Trouble falling asleep at bedtime
  • Waking often during the night or waking too early and being unable to fall back asleep
  • Lying awake for long stretches
  • Feeling unrefreshed after a full night in bed
  • Daytime fatigue, low energy, or sleepiness
  • Irritability, anxiety, or trouble concentrating and remembering

When these symptoms persist most nights and interfere with daily life, it is worth a medical evaluation.

How does Avita MD diagnose and treat insomnia?

At Avita MD, evaluation starts with a careful sleep history and your daily routine, often supported by a sleep diary that tracks bedtime, wake time, and nighttime awakenings. We look for treatable causes such as stress, anxiety, depression, caffeine or alcohol, medications, chronic pain, acid reflux, or another sleep disorder. On-site lab testing lets us check for contributors like thyroid problems or anemia in the same visit. When signs point to sleep apnea or restless legs syndrome, we coordinate a sleep study and specialist referral.

Treatment focuses first on the habits that drive better sleep. Cognitive behavioral therapy for insomnia and a steady sleep schedule are the most effective long-term approaches, and medication can help for short periods when appropriate. Same-day and next-day appointments mean a new sleep problem can be addressed quickly, and we track your progress over time through longitudinal records so we can adjust the plan as your sleep improves.

These everyday habits support healthy sleep:

Helpful sleep habitsBest to avoid before bed
Keep a regular sleep and wake timeCaffeine in the afternoon and evening
Keep the bedroom dark, quiet, and coolAlcohol and large meals late at night
Get daytime light and regular activityScreens and bright light at bedtime
Use the bed only for sleepLong daytime naps

When should you see a doctor about insomnia?

Schedule a visit when sleep problems last more than a few weeks, happen most nights, or begin to affect your mood, focus, work, or safety. Seek care sooner if you find yourself falling asleep during the day while driving or working, or if a partner notices loud snoring with pauses in breathing, which can signal sleep apnea. Addressing insomnia early protects your daytime function and your long-term health, and most people improve with the right plan.

Insomnia: Frequently Asked Questions

What is the difference between short-term and chronic insomnia?

Short-term, or acute, insomnia lasts a few days to a few weeks and is often triggered by stress, travel, or a change in routine. Chronic insomnia means trouble sleeping at least three nights a week for three months or longer. Chronic insomnia is more likely to need ongoing evaluation and treatment.

What causes insomnia?

Insomnia can be caused by stress, anxiety, depression, an irregular schedule or shift work, caffeine or alcohol, certain medications, and medical conditions such as chronic pain, acid reflux, or another sleep disorder. Many cases are secondary, meaning they stem from an underlying issue that can be treated.

How is insomnia treated?

First-line treatment is cognitive behavioral therapy for insomnia along with a regular sleep schedule and good sleep habits. Medication may be added for short periods when needed. Treating any underlying medical or mental health condition is an important part of lasting improvement.

Do I need a sleep study to diagnose insomnia?

Most insomnia is diagnosed from your sleep history and a sleep diary, without a sleep study. A sleep study is ordered when signs point to another disorder such as sleep apnea or restless legs syndrome. Your Avita MD provider will advise whether testing is needed.

When should I see a doctor about poor sleep?

See a doctor when sleep problems last more than a few weeks, happen most nights, or affect your mood, focus, or daytime functioning. Seek care sooner if you fall asleep during daily activities or if loud snoring and pauses in breathing suggest sleep apnea.
