Insomnia and other health concerns may be linked to liver stiffness, a condition that affects an estimated 10% of women and can be exacerbated by stress, alcohol consumption, and perimenopause, according to recent health insights.
A fibroscan, an ultrasound test used to measure liver fat and scarring, can reveal the health of the liver. For one individual, despite a normal liver fat score, the test indicated potential issues with liver stiffness, prompting a closer look at contributing factors.
The Liver's Role in Stress and Health
Experts suggest the liver acts as a physiological stress absorber, processing hormonal and inflammatory compounds that result from emotional, physical, and environmental stressors. Over time, this cumulative burden can lead to increased liver fat, inflammation, and stiffness, impacting overall health. This stress processing by the liver can also affect blood sugar and cortisol regulation throughout the night, potentially contributing to sleep disturbances such as waking up at 3 a.m.
Factors Influencing Liver Stiffness
While alcohol consumption is a known factor impacting liver health, lifestyle and stress also play significant roles. The physical demands of daily life, combined with hormonal changes like perimenopause, can place additional strain on the liver. A US study noted that liver stiffness can increase during menopause, and alcohol use further contributes to this risk.
A normal liver fibroscan for stiffness typically ranges from 2-7 kilopascals (kPa), indicating no or minimal scarring. Scores above 8 kPa suggest elevated stiffness, which can disrupt normal liver function.
Potential Interventions and Lifestyle Changes
While supplements designed to enhance the liver's metabolic capacity are available, their efficacy and cost-effectiveness remain subjects of personal assessment. Some individuals find that after a period of use, they experience benefits such as reduced hangovers and increased energy. However, traditional lifestyle adjustments like weight loss, a healthier diet, increased exercise, and moderating alcohol intake are also cited as effective strategies for improving liver health and reducing inflammation and scarring.
Experts recommend that for individuals experiencing persistent insomnia or other concerning symptoms, a medical evaluation, including tests like the fibroscan, can provide valuable insights into potential underlying liver issues.
