26 the guardians Insomnia as you age COMPLAINTS of poor sleep or excessive daytime sleepiness are more common in older persons. The elderly endure significant changes to their established sleep/ wake patterns such as retirement, reductions in physical and social activity and in some cases institutionalisation. Surveys have shown 26 to 45 per cent of older people complain of insomnia. Changes in sleep as a result of ageing The most striking age related change in sleep physiology is a reduction in the amount and amplitude of delta sleep. Compared with younger persons, elderly persons spend more time in bed relative to the amount of time they are actually asleep. “Although the elderly do not require more time to fall asleep (sleep latency), they awaken more frequently during the night and stay awake longer. They may nap more during the day and are more sensitive to changes in time zones and other environmental cues,” says Pantai Hospital Kuala Lumpur Consultant Physi- cian and Geriatrician Dato Dr Rajbans Singh. CARP.CA The HEALTH | NOVEMBER, 2018 Metabolic syndrome in persons 60 years and above Abdominal obesity and high blood pressure among the common symptoms D O you feel tired? Do you feel fatigued and lethargic? Do you have a fuzzy mind? Are you reaching middle-age? These are a few of the symptoms of a new disorder – meta- bolic syndrome. Pantai Hospital Kuala Lumpur Con- sultant Physician and Geriatrician Dato Dr Rajbans Singh revealed that this syndrome goes by many other names – Syndrome X, Dysmetabolic syndrome, insulin resistance syndrome, obesity syndrome and Reaven’s syndrome. What is metabolic syndrome? Because sleep disturbances are often transient responses to situational stresses or new surroundings, only disturbances persisting more than one month are considered clinically significant. Factors which disturb sleep patterns include anxiety, depression, pain, dis- comfort due to constipation, urgency, frequency, nocturia, restless legs, cramps, daytime napping, nocturnal cough or breathlessness and unrealistic expectations. Treatment of insomnias The most important principle in manag- ing insomnia is to consider sleeping pills as last resort. Rajbans explained that the aim of non- pharmacologic measures is to strengthen the association of time spent in bed with sleeping and to weaken its association with activities incompatible with sleep (worrying, lying awake). These goals can be met with careful attention to sleep hygiene - regular schedule of going to sleep and arising, even on weekends and holidays. “The sleeping area should be kept at a comfortable temperature and as noise free as possible. It is just as important that the bed not be associated with the frustra- tion of trying to get to sleep. This means not using the bed for non-sleep activities such as reading or watching television.” “Good sleep hygiene also includes avoiding nocturia by limiting the inges- tion of fluids such as caffeine and tobacco which can interfere with sleep when taken to late in the evening. SCIENCE NEWS FOR STUDENTS It is a cluster of related syndromes which can cause an individual to be susceptible to a series of medical night- mares such as heart disease, stroke, diabetes, kidney diseases, clogged arteries and premature death. The symptoms of a metabolic syn- dromes are: 1. Central / abdominal obesity as mea- sured by weight circumference. Men greater then 40 inches (120cm) and women greater than 35 inches (88cm). 2. Fasting triglycerides (bad choles- terol) greater than or equal to 150mg / dL. five symptoms. If left untreated, the medical complications can develop in as few as 15 years. It can affect any age but most frequently those who are significantly overweight with most of the excess fat in the abdominal area and are inactive.” Rajbans emphasised that for per- sons 60 years and above, it’s going to be harder to lose weight because your hormone drops, and the inability to exercise due to other medical problems would compound the problem.” Who is at risk? Dr Rajbans emphasised that for persons 60 years and above, it’s going to be harder to lose weight because your hormone drops. 3. HDL cholesterol (good cholesterol) – men less than 40mg/dL while women less than 50mg/dL. 4. Blood pressure greater than or equal to 130/85mm Hg. 5. Fasting glucose greater than or equal to 110mg /dL. “A diagnosis of metabolic syndrome is made if one fulfils three out of the “The prevalence increases with age affecting less than 10 per cent of people in their 20s and 40 per cent in their 60s. Body mass index (BMI) is a measure of your percentage of body fat based on height and weight. If the BMI is greater than 25 it increases the risk of metabolic syndrome. In addition to these, those with gestational diabetes (diabetes during pregnancy) and family history of type 2 diabetes are likely to develop metabolic syndrome.” Hypertension, cardio vascular dis- ease and polycystic ovarian syndrome – a hormonal disorder in which the ovaries produce an excess of male hor- mones increases the risk of metabolic syndrome. Walking and aerobics helps prevent metabolic syndrome M ETABOLIC Syndrome is a slow progressive syndrome that may take as long as 15 years before it appears in a full spectrum. “Therefore in alignment with all medical diseases, prevention is better than cure. You can curb your insulin resistance by just taking control and making lifestyle changes such as walking just 30 minutes everyday or engaging in any aerobic activity,” explained Pantai Hospital Kuala Lumpur Consultant Physician and Geriatrician Dato Dr Rajbans Singh. “By just loosing as little as five per cent to 10 per cent of your body weight one can reduce insulin levels, high blood pressure and decrease the risk of diabetes. Smoking ciga- rettes creates an increase in insulin resistance and hence worsens the health consequences of metabolic WHEREYOULIVEMATTERS.ORG syndrome. In addition, thinking and eating sensibly is a good tip for a healthy lifestyle. Ensure that your grocery cart includes whole grains, beans, fruits and vegetables. These items are rich with dietary fiber which helps in lowering the insulin levels.
