If you often feel that your sense of taste has changed, your mouth is dry and there is a peculiar taste in your mouth, be wary about the possibility that you have dry mouth syndrome (xerostomia). Ko Hui-hsin, an attending physician in the dentistry department at National Taiwan University Hospital’s Hsinchu Branch, says that middle-aged women over the age of 50 make up the majority of people suffering from dry mouth. The main symptoms include dryness in the mouth, dry eyes, dry genitalia and aching joints. The causes of dry mouth are complex and it is best to get tested at a hospital instead of ignoring the condition, she says.
Ko says that saliva fights bacteria and helps keep the teeth and mouth clean. When salivation is reduced, however, the oral mucosa can get irritated and food builds up on the teeth, which allows bacteria to breed, and causes bad breath (halitosis), cavities, bleeding gums and periodontal disease. In more serious cases, it can cause difficulties chewing and swallowing, leading to malnutrition and affecting one’s overall health, Ko says, adding that dry mouth can also serve as a signal for latent diseases.
Dry mouth can be caused by salivary gland stones, she says, adding that when salivary stones form, the gland’s ability to secrete is impeded, which in turn causes dryness in the mouth, as well as pain and swelling under the tongue and in the cheeks. People with iron-deficiency anemia have relatively paler and shinier, smoother tongues, accompanied by symptoms such as burning, stabbing pains and dryness in the mouth, while people with pernicious anemia in its early stages experience numbness in the tongue, depapillation of the tongue and dryness in the mouth.
Diabetics typically suffer from frequent urination, dry mouth and abnormal hunger. If you have a history of diabetes in your family or are overweight, it must be taken seriously, Ko says. Approximately 30 percent of seniors have various degrees of dry mouth due to a decrease in the secretion of saliva caused by atrophy in the salivary glands.
Ko says that symptoms can be improved in most cases of dry mouth by eliminating the cause, regardless of whether the condition is due to physiological disorders or systematic diseases. It is impossible to completely cure cases of dry mouth brought on by age, she says, recommending that one place more importance on keeping the mouth clean and using fluoride toothpaste. Although drinking more water can help lessen the discomfort associated with dry mouth, seniors, and people with bad livers and hearts, should be careful and avoid drinking excessive amounts of water, which can increase the burden put on internal organs.

Chinese automobile manufacturer Zotye Auto is a household name in China. The company is famous for manufacturing copies of car models by luxury international brands including Audi, Porsche and Lamborghini. After a long delay, on June 22, Zotye Auto finally released its 2019 year end financial results. The report revealed that last year, the automaker suffered losses of 11.2 billion yuan (approximately NT$46.6 billion), or an average of 30 million yuan per day. The company’s market value also shrank from 30 billion yuan to a mere 3.6 billion yuan. Even worse, because the company is unable to guarantee the authenticity,
Forget your pepperoni or other pizza toppings: Pizza Hut Taiwan has teamed up with Menya Musashi, a popular Japanese ramen restaurant chain, to serve up the world’s first ramen pizza, and it has attracted global interest after a CNN report about the new mashup was published on the front-page of its Japanese version. The new pizza has the toppings of a Japanese-style barbecue pork ramen — complete with thick noodles, barbecue pork slices, fresh chilies and white sesame, as well as a half-boiled egg sitting in the middle. It is also garnished with green onions and bamboo shoots on the side. Pizza
Segway Inc. announced last week that it will end production of its iconic two-wheeled personal vehicle starting July 15. When the company launched the product nearly two decades ago, it boldly claimed that its namesake two-wheeler would revolutionize the way people move, but it only sold 140,000 units across the world. The Segway was criticized for the high price tag of US$4,950 (about NT$147,000). It was also challenging to ride, because riders must maintain a balance at a specific angle for the vehicle to move forward, and can easily be thrown off if they lose control. Several months after buying the
Europe has lost a vastly increased area of forest to harvesting in recent years, data suggest, reducing the continent’s carbon absorption capacity and possibly indicating wider problems with the EU’s attempts to combat the climate crisis. Many of the EU’s forests — which account for about 38 percent of its land surface area — are managed for timber production, and thus harvested regularly. But the loss of biomass increased by 69 percent in the period from 2016 to 2018, compared with the period from 2011 to 2015, according to satellite data. The area of forest harvested increased by 49 percent in
