Overview â The distinctive tiger shark lives in both coastal and open seawaters, usually from the surface to around 459 feet. Young members of this species sport black stripes arranged over their otherwise gray backs and sides. These stripes can fade as the shark ages, making it look more like a great white than a tiger shark. Somehow it seems appropriate that this nocturnal, aggressive shark prefers dark, murky waters.
The World Cancer Research Fund concluded that obesity is probably linked to an increased risk of aggressive prostate cancer, based on a 2014 meta-analysis of all the evidence [77]. Obesity isn't linked with risk of prostate cancer overall.
Medical Causes of Obesity Obesity is usually the result of overeating, but in a small percentage of people excess weight gain is a symptom of another disease. Medical causes of obesity can include: Hypothyroidism. This is a condition where the thyroid gland, located in the neck, produces too little thyroid hormone. Thyroid hormone regulates our metabolism. So too little hormone slows the metabolism and often causes weight gain.
