Pulmonology focuses on diagnosing and treating lung and airway conditions such as asthma, COPD, and pneumonia, as well as overall respiratory health.

The clinical presentation of sleep apnea is often first noticed by a bed partner rather than by the patient. The symptoms can range from subtle signs, such as morning headaches, to overt disruptions, such as loud gasping during sleep. Identifying the risk factors is crucial for screening and early diagnosis. At Liv Hospital, we emphasize a comprehensive assessment of both nighttime behaviors and daytime functioning to build a complete clinical picture. Understanding the diverse symptoms, from cognitive changes to cardiovascular strain, helps in recognizing the full impact of this disorder.
The symptoms that occur during sleep are the direct result of the airway obstruction or central nervous system failure.
Nocturia: Frequent nighttime trips to the bathroom are common. The strain on the heart triggers the release of a hormone that signals the kidneys to produce more urine.
The disruption of sleep architecture leads to significant daytime impairment.
Specific physical characteristics predispose individuals to airway collapse.
Modifiable factors play a massive role in the development and severity of sleep apnea.
Some risk factors are inherent and cannot be changed.
Race: In the US, sleep apnea is more common in African Americans, Hispanics, and Native Americans under the age of 35 compared to Caucasians of the same age.
Certain medical conditions are strongly associated with sleep apnea.
Women may present differently from men, leading to underdiagnosis.
Misdiagnosis: Because they don’t fit the “typical” profile (loudly snoring male), women are often misdiagnosed with anxiety, depression, or simple insomnia.

CT scans use X-rays to create detailed cross-sectional images and are excellent for visualizing kidney stones, detecting tumors, and evaluating traumatic injuries. They are fast and widely available. MRI uses strong magnetic fields and radio waves to produce detailed images of soft tissues, making it superior for staging prostate cancer, evaluating bladder wall invasion, and assessing pelvic floor disorders without ionizing radiation.
Contrast dye, usually iodine-based, is injected into a vein to highlight the blood vessels and urinary tract organs. As the kidneys filter the dye from the blood, it opacifies the urine. This allows the radiologist to see the internal structure of the kidneys, the ureters, and the bladder clearly, revealing blockages, tumors, or structural abnormalities that would be invisible on a non-contrast scan.
Multiparametric MRI is an advanced imaging technique that combines standard anatomical sequences with functional sequences like Diffusion-Weighted Imaging and Dynamic Contrast-Enhanced imaging. This provides a comprehensive assessment of the prostate, allowing doctors to distinguish between benign conditions like BPH and significant prostate cancer, and to guide targeted biopsies.
CT scans do involve exposure to ionizing radiation, which carries a small theoretical risk of cellular damage over time. However, modern CT scanners use dose-modulation technology to minimize this exposure to the lowest level necessary for a diagnostic image. The benefit of an accurate and timely diagnosis for serious urological conditions typically far outweighs the minimal risk of radiation.
Many modern orthopedic implants are MRI-safe, although they may cause some image distortion. However, older pacemakers, defibrillators, and certain metal clips may be unsafe in the strong magnetic field. It is critical to inform the imaging team of any metallic implants so they can verify their safety compatibility or recommend an alternative test like a CT scan.
