Possible Causes of Anxiety and Insomnia

Conditions that commonly cause both symptoms together

1Early Hyperthyroidism often produces non-specific symptoms: fatigue, malaise, or mild discomfort
2Early warning signs may include: palpitations, weight loss, anxiety, tremor
3Subclinical changes in blood tests, blood pressure, or weight often precede overt symptoms
4Family history and risk factors increase the probability that vague symptoms represent early Hyperthyroidism
5Screening programmes are designed specifically to detect Hyperthyroidism before symptoms appear
6Core management targets: reducing palpitations, weight loss, anxiety and preventing disease progression

Emergency Red Flags

Seek immediate medical attention if you experience any of these

Any of the characteristic symptoms of Hyperthyroidism — even mild — in a high-risk individual

Progressive worsening of early warning signs over weeks

Laboratory abnormalities (e.g., blood sugar, inflammatory markers) without full symptoms

Unexplained weight loss, night sweats, or fatigue persisting >2 weeks

Strong family history of Hyperthyroidism combined with new relevant symptoms

When to See a Doctor

Schedule a medical consultation if you notice these signs

You have risk factors for Hyperthyroidism and develop any of the characteristic early symptoms

Screening tests return borderline or abnormal results

You have a strong family history and have not yet been screened for Hyperthyroidism

Scheduled monitoring appointments — do not skip even when feeling well

Conditions That Cause Both Anxiety and Insomnia

9 conditions are associated with this symptom combination

Hyperthyroidism

Hyperthyroidism occurs when the thyroid gland produces too much thyroid hormone, speeding up metabolism. It causes weight loss, rapid heartbeat, anxiety, tremors, and heat intolerance. Graves' disease is the most common cause.

Depression is a common and serious mood disorder causing persistent feelings of sadness, hopelessness, and loss of interest in activities. It affects how a person thinks, feels, and handles daily activities. Effective treatments include therapy and medication.

Anxiety Disorder

Anxiety disorders are among the most common mental health conditions, characterized by excessive fear, worry, or nervousness that interferes with daily activities. Types include generalized anxiety disorder (GAD), panic disorder, and social anxiety.

Post-Traumatic Stress Disorder (PTSD)

PTSD develops after exposure to traumatic events, causing intrusive memories, nightmares, hypervigilance, avoidance, and emotional numbing. Trauma-focused cognitive behavioral therapy and EMDR are evidence-based treatments.

Obsessive-Compulsive Disorder (OCD)

OCD is characterized by intrusive obsessional thoughts and compulsive rituals performed to reduce anxiety. It affects 2-3% of the population; exposure and response prevention (ERP) therapy combined with SSRIs is the gold standard treatment.

ADHD (Attention Deficit Hyperactivity Disorder)

ADHD is a neurodevelopmental disorder causing inattention, hyperactivity, and impulsivity that impairs academic, occupational, and social functioning. Stimulant medications (methylphenidate, amphetamine salts) combined with behavioral therapy are effective.

Substance Use Disorder

Substance use disorder involves compulsive use of substances despite harmful consequences, including alcohol, opioids, stimulants, and cannabis. It is a chronic brain disorder; treatment includes behavioral therapies, medications (methadone, naltrexone, buprenorphine), and support groups.

Magnesium Deficiency

Magnesium deficiency affects an estimated 10-30% of the population. Magnesium is involved in over 300 enzymatic reactions in the body, making deficiency wide-ranging in effects.
