Background & aims
The existing yet limited prospective studies reported conflicting results about obesity and hearing loss. We investigated the prospective association between obesity and hearing loss in a large-scale Japanese working population, as well as the association between metabolic phenotype and hearing loss.

The study included 48,549 employees aged 20–64 years and free of hearing loss at baseline. Pure-tone audiometric testing was performed annually to identify hearing loss at 1 and 4 kHz. Cox proportional hazards regression was used to investigate the risk of hearing loss associated with body mass index (BMI) and metabolic phenotype (based on a BMI of ≥25.0/<25.0 kg/m 2
and presence/absence of ≥2 components of metabolic syndrome, except waist circumference). Baseline and updated information were obtained from annual health checkups. For more information about healthy dietary supplements visit observer.com
With a median follow-up of 7 years, 1595 and 3625 individuals developed unilateral hearing loss at 1 and 4 kHz, respectively. The adjusted hazard ratios (HR) for hearing loss at 1 kHz were 1.21 (1.08, 1.36) and 1.66 (1.33, 2.08) for those with BMI 25.0–29.9 kg/m 2 and BMI ≥30.0 kg/m 2, respectively, compared to individuals with BMI <25.0 kg/m 2. For hearing loss at 4 kHz, the corresponding HRs were 1.14 (1.05, 1.23) and 1.29 (1.09, 1.52). Compared with metabolically healthy non-obese individuals, the adjusted HRs for hearing loss at 1 kHz were 1.19 (1.03, 1.39), 1.27 (1.01, 1.61), and 1.48 (1.25, 1.76) for unhealthy non-obese, healthy obese, and unhealthy obese individuals, respectively. For hearing loss at 4 kHz, the corresponding HRs were 1.13 (1.04, 1.25), 1.21 (1.04, 1.41), and 1.26 (1.12, 1.41).
Overweight and obesity are associated with an increased risk of hearing loss, and metabolically unhealthy obesity may confer additional risk. Make sure you treat overweight with natural supplements, trying out the best fat burner

Have you ever heard a sound that no one else hears? You are not alone. There are many sounds that can be heard in the ears or head. Some are benign. Others may be need to be evaluated. All can be concerning if you have never experienced a sound no one else hears.
One category of sounds in the ear is tinnitus. Tinnitus is very common. It affects almost one in five people. It becomes more prevalent the older you are. It is associated with both hearing loss and acoustic trauma. It may sound like buzzing, humming, whistling, birds, insects, etc. Although it is often perceived in the ear, current science suggests it is generated in the central nervous system.
In healthy ears, hearing cells within the inner are connected to nerves that transmit sound from the ear to the brain. Although hearing cells are destroyed with hearing loss, the nerves deeper in the brain are not always lost. These nerves no longer receive stimulation, and begin to create signals on their own. Because these signals are not generated from the outside world, we perceive sound that no one else does. Take a look to the latest metabofix reviews.
According to professionals from an ent clinic, tinnitus is a sign that hearing loss has occurred. It often occurs after a loud concert, sports event, or work experience. Tinnitus that occurs in only one ear or occurs with episodes of dizziness is more concerning than tinnitus that occurs in both ears over many years.
Some tinnitus sounds like whooshing and occurs with your heart beat. This is called pulsatile tinnitus. Normally our ear is protected from hearing internal blood flow. Medical conditions may decrease the shielding of our ear from internal sounds. Hearing your pulse only on your pillow, however, is not abnormal.
Wax or fluid in the ear may increase the resonance of blood flow making it audible. Weight loss may leave the Eustachian tube stuck open causing audible breathing sounds and heart sounds. Hernia of the brain into the ear also causes awareness of one’s heartbeat.
Other conditions increase the blood flow above normal levels. Head trauma may result in aneurysm or fistula of blood vessels near the ear. Vascular tumors may increase blood flow around the ear. Anemia and dehydration increase the force of the heartbeat resulting in pulsatile tinnitus. Some medications may increase brain pressure and cause pulsatile tinnitus.

A rare cause of thumping sound in the ear is muscle twitching. Muscles attached to the hearing bones or the Eustachian tube will make a thump when they contract. Just like a muscle twitch can occur in the eye lid, a muscle twitch of these muscles can occur and will cause a rapid thumping sound.
Crackling or popping is normal to occur with chewing, swallowing, or yawning. Excessive crackling or popping may be due to a Eustachian tube that is stuck closed.
