轉貼文章 ~ 「四種預防方法」讓眼睛雪亮終生!


皮相的老化以皺紋呈現,年齡的老化以智慧展現,而眼球水晶體的老化,則以白內障展現。根據「全民健康基金會」說明,台灣50歲以上的人60%患有白內障、60歲以上80%70歲以上更高達90%,可見白內障侵襲台灣人的程度。

白內障症狀與種類

白內障初期症狀難以察覺,需要經過非常細微的檢測才能發現。
而在更進一步的症狀開始出現後,會感到陽光、燈光等光線顯得明亮眩目等,而進而影響生活、視力。
通常近視度數會暴增數百度,某些狀況下患者視力會突然變好(近視度數減低)
,但這不是個好兆頭:隨後將帶來更嚴重的病變,若不進行治療,可能引發青光眼,甚至失明。
根據國外健康網站「Allaboutvision」講解,白內障主要分成三種:
l   囊下白內障:發生於水晶體後方,糖尿病患者或攝取高劑量類固醇者有較高機率獲得此症。
l   核性白內障:通常因年紀因素所致,從水晶體中央開始生成。
l   皮質性白內障:該類白內障從水晶體四周開始生成,圍繞著水晶體中心,並佔據水晶體皮質。



十二種人需注意 高血壓 高度近視皆上榜

什麼樣的人是高危險群?Allaboutvision表示,以下十二種人,到一定年紀後將更有白內障風險:
l   長時間、長期直視、接觸紫外線
l   糖尿病
l   高血壓
l   肥胖
l   抽菸
l   使用皮脂類固醇藥物
l   服用降血脂藥物
l   眼球曾受傷、動手術
l   荷爾蒙療法
l   大量酒精攝取
l   高度近視
l   家族病史

四種預防方法 保護眼睛

維他命C
柳橙汁內富含豐富的維他命C,與而維他命C的攝取多寡與白內障發生機率成反比。《營養學期刊》(Journal of Nutrition)內研究便指出,攝取高劑量的維他命C,可以有效預防超過六成的白內障發生機率。
             
茄紅素
雖然效果不如維他命C,但同一份研究指出,如番茄、西瓜(是的──西瓜不僅有茄紅素,其茄紅素含量還是番茄的1.5倍!)等含有茄紅素的水果,也能夠降低46%的白內障發生機率。

降低醣類
減少碳水化合物的攝取,對於維護視力、預防白內障有所幫助。根據期刊《IVOS(Investigative Ophthalmology & Visual Science)指出,大量攝取醣類的族群比起少量攝取醣類的族群,罹患白內障的機率足足差了三倍之多。

多喝茶
綠茶、紅茶在《農業與食品科學期刊》(Journal of Agricultural and Food Chemistry)中,經過動物實驗之後,被研究出能夠抑制糖尿病造成的白內障。

Carbohydrate Counting & Diabetes

What is carbohydrate counting?

Carbohydrate counting, also called carb counting, is a meal planning tool for people with type 1 or type 2 diabetes. Carbohydrate counting involves keeping track of the amount of carbohydrate in the foods you eat each day.
Carbohydrates are one of the main nutrients found in food and drinks. Protein and fat are the other main nutrients. Carbohydrates include sugars, starches, and fiber. Carbohydrate counting can help you control your blood glucose, also called blood sugar, levels because carbohydrates affect your blood glucose more than other nutrients.
Healthy carbohydrates, such as whole grains, fruits, and vegetables, are an important part of a healthy eating plan because they can provide both energy and nutrients, such as vitamins and minerals, and fiber. Fiber can help you prevent constipation, lower your cholesterol levels, and control your weight.
Unhealthy carbohydrates are often food and drinks with added sugars. Although unhealthy carbohydrates can also provide energy, they have little to no nutrients. More information about which carbohydrates provide nutrients for good health and which carbohydrates do not is provided in the NIDDK health topic, Diabetes Diet and Eating.
The amount of carbohydrate in foods is measured in grams. To count grams of carbohydrate in foods you eat, you’ll need to
  • know which foods contain carbohydrates
  • learn to estimate the number of grams of carbohydrate in the foods you eat
  • add up the number of grams of carbohydrate from each food you eat to get your total for the day
Your doctor can refer you to a dietitian or diabetes educator who can help you develop a healthy eating plan based on carbohydrate counting.

Which foods contain carbohydrates?

Foods that contain carbohydrates include
  • grains, such as bread, noodles, pasta, crackers, cereals, and rice
  • fruits, such as apples, bananas, berries, mangoes, melons, and oranges
  • dairy products, such as milk and yogurt
  • legumes, including dried beans, lentils, and peas
  • snack foods and sweets, such as cakes, cookies, candy, and other desserts
  • juices, soft drinks, fruit drinks, sports drinks, and energy drinks that contain sugars
  • vegetables, especially “starchy” vegetables such as potatoes, corn, and peas
Potatoes, peas, and corn are called starchy vegetables because they are high in starch. These vegetables have more carbohydrates per serving than nonstarchy vegetables.
Examples of nonstarchy vegetables are asparagus, broccoli, carrots, celery, green beans, lettuce and other salad greens, peppers, spinach, tomatoes, and zucchini.
Foods that do not contain carbohydrates include meat, fish, and poultry; most types of cheese; nuts; and oils and other fats.

Foods that contain carbohydrates include grains,fruits, dairy products, vegetables, and legumes.

What happens when I eat foods containing carbohydrates?

When you eat foods containing carbohydrates, your digestive system breaks down the sugars and starches into glucose. Glucose is one of the simplest forms of sugar. Glucose then enters your bloodstream from your digestive tract and raises your blood glucose levels. The hormone insulin, which comes from the pancreas or from insulin shots, helps cells throughout your body absorb glucose and use it for energy. Once glucose moves out of the blood into cells, your blood glucose levels go back down.

How can carbohydrate counting help me?

Carbohydrate counting can help keep your blood glucose levels close to normal. Keeping your blood glucose levels as close to normal as possible may help you
  • stay healthy longer
  • prevent or delay diabetes problems such as kidney disease, blindness, nerve damage, and blood vessel disease that can lead to heart attacks, strokes, and amputations—surgery to remove a body part
  • feel better and more energetic
You may also need to take diabetes medicines or have insulin shots to control your blood glucose levels. Discuss your blood glucose targets with your doctor. Targets are numbers you aim for. To meet your targets, you will need to balance your carbohydrate intake with physical activity and diabetes medicines or insulin shots.

How much carbohydrate do I need each day?

The daily amount of carbohydrate, protein, and fat for people with diabetes has not been defined—what is best for one person may not be best for another. Everyone needs to get enough carbohydrate to meet the body’s needs for energy, vitamins and minerals, and fiber.
Experts suggest that carbohydrate intake for most people should be between 45 and 65 percent of total calories. People on low-calorie diets and people who are physically inactive may want to aim for the lower end of that range.
One gram of carbohydrate provides about 4 calories, so you’ll have to divide the number of calories you want to get from carbohydrates by 4 to get the number of grams. For example, if you want to eat 1,800 total calories per day and get 45 percent of your calories from carbohydrates, you would aim for about 200 grams of carbohydrate daily. You would calculate that amount as follows:
  • .45 x 1,800 calories = 810 calories
  • 810 ÷ 4 = 202.5 grams of carbohydrate
You’ll need to spread out your carbohydrate intake throughout the day. A dietitian or diabetes educator can help you learn what foods to eat, how much to eat, and when to eat based on your weight, activity level, medicines, and blood glucose targets.

Drawing of a female registered dietitian consulting with a male patient.

How can I find out how much carbohydrate is in the foods I eat?

You will need to learn to estimate the amount of carbohydrate in foods you typically eat. For example, the following amounts of carbohydrate-rich foods each contain about 15 grams of carbohydrate:
  • one slice of bread
  • one 6-inch tortilla
  • 1/3 cup of pasta
  • 1/3 cup of rice
  • 1/2 cup of canned or fresh fruit or fruit juice or one small piece of fresh fruit, such as a small apple or orange
  • 1/2 cup of pinto beans
  • 1/2 cup of starchy vegetables such as mashed potatoes, cooked corn, peas, or lima beans
  • 3/4 cup of dry cereal or 1/2 cup cooked cereal
  • 1 tablespoon of jelly
Some foods are so low in carbohydrates that you may not have to count them unless you eat large amounts. For example, most nonstarchy vegetables are low in carbohydrates. A 1/2-cup serving of cooked nonstarchy vegetables or a cup of raw vegetables has only about 5 grams of carbohydrate.
As you become familiar with which foods contain carbohydrates and how many grams of carbohydrate are in food you eat, carbohydrate counting will be easier.

Nutrition Labels

You can find out how many grams of carbohydrate are in the foods you eat by checking the nutrition labels on food packages. Following is an example of a nutrition label:

Sample nutrition label for macaroni and cheese showing a serving size of 1 cup and total carbohydrate amount of 31 grams.
Nutrition labels tell you the total grams of carbohydrate per serving, along with other nutrition information.

Nutrition labels tell you
  • the food’s serving size––such as one slice or 1/2 cup
  • the total grams of carbohydrate per serving
  • other nutrition information, including calories and the amount of protein and fat per serving
If you have two servings instead of one, such as one cup of pinto beans instead of 1/2 cup, you multiply the number of grams of carbohydrate in one serving—for example, 15—by two to get the total number of grams of carbohydrate—30.
15 x 2 = 30

Cooking at Home

To find out the amount of carbohydrate in homemade foods, you’ll need to estimate and add up the grams of carbohydrate from the ingredients. You can use books or websites that list the typical carbohydrate content of homemade items to estimate the amount of carbohydrate in a serving.
You can also weigh foods with a scale or measure amounts with measuring cups or spoons to estimate the amount of carbohydrate. For example, if a nutrition label shows that 1 1/2 cups of cereal contain 45 grams of carbohydrate, then 1/2 cup will have 15 grams of carbohydrate and 1 cup will have 30 grams of carbohydrate.

Eating Out

Some restaurants provide nutrition information that lists grams of carbohydrate. You can also use carbohydrate counting food lists to estimate the amount of carbohydrate in restaurant meals. 

Can I eat sweets and other foods and drinks with added sugars?

Yes, you can eat sweets and other foods and drinks with added sugars. However, you should limit your intake of these high-carbohydrate foods and drinks because they are often high in calories and low in vitamins, minerals, and fiber. Fiber-rich whole grains, fruits, vegetables, and beans are wiser choices.
Instead of eating sweets every day, try eating them in small amounts once in a while so you don’t fill up on foods that are low in nutrition. Ask your dietitian or diabetes educator about including sweets in your eating plan.

How can I tell whether carbohydrate counting is working for me?

Checking your blood glucose levels can help you tell whether carbohydrate counting is working for you. You can check your blood glucose levels using a glucose meter.
You should also have an A1C blood test at least twice a year. The A1C test reflects the average amount of glucose in your blood during the past 3 months.
If your blood glucose levels are too high, you may need to make changes in your eating plan or other lifestyle changes. For example, you may need to make wiser food choices, be more physically active, or make changes to your diabetes medicines. Talk with your doctor about what changes you need to make to control your blood glucose levels.
If you use an insulin pump or take more than one daily insulin shot, ask your doctor how to adjust your insulin when you eat something that isn’t in your usual eating plan.

Can I use carbohydrate counting if I am pregnant?

You can use carbohydrate counting to help control your blood glucose levels when you are pregnant. Meeting your blood glucose targets during pregnancy is important for your and your baby’s health. High blood glucose during pregnancy can harm the baby and increase the baby’s chances of having type 2 diabetes later in life.
Women diagnosed with gestational diabetes—a type of diabetes that develops only during pregnancy—can also use carbohydrate counting to help control their blood glucose levels.
Talk with your doctor about using carbohydrate counting to help meet your blood glucose targets during your pregnancy.

轉貼文章 ~ 食神教路:白砂糖為百病之根本 毒性極高「牲畜一食即死」

大家外出食飯又好,喺屋企煮飯又好,都會用白砂糖喺食物及飲品度,久而久之用到慣,有時飲杯奶茶咖啡都落兩包,以為剩係因為甜對身體唔好會肥?其實無你諗得咁簡單,因為白砂糖係完全化學提煉,其本上係化學毒物!
白砂糖由炭、亞硫酸、二氧化硫加埋蔗汁煮乾,然後再加有氯、酸鹽,再經漂白成白色而成;當中蔗汁嘅礦物質及維生素全部流失,可以話白砂糖根本係化學物品。日本就一直有研究指,白砂糖係百病之根本,所以日本國內極少使用,更有人話呢個係日本人長壽原因之一。美國農牧業學會更講過,白砂糖係百害而無一利;一旦動物食咗,必定死亡。咁究竟白砂糖被確實嘅壞處有咩呢?大家睇下啦!
失眠、暴躁
當白砂糖進入體內,身體血糖指數暴升,因為身體會自制胰島素令血糖下降,但反而令血糖下降得太嚴重,身體又會自制腎上腺素令血糖提升,結果令身體長體興奮,出現失眠、暴躁等症狀。
缺鈣、蛀牙
白砂糖酸性特強,食用後身體會以鈣質去中和酸性,令身體缺鈣,當然牙齒會變成易蛀牙之外,身體骨頭缺鈣亦非易嚴重,尤其老咗後更易有骨質疏鬆嘅情況出現!
暈眩、疲倦
糖要分解,必須大量維他命B;而白砂糖係重度糖量,含醣量極高,尤其需要大量維他命B,以到身體長期疲倦、暈眩、貧血、記憶力衰退等問題。

轉貼文章 ~ 腳底養生,讓你百病全消

中醫腳底養生有兩個特色:

其一是任何人都可以隨時隨地履行,按壓搓和敲擊的方式很輕易控制,費時未幾。
其二是以中醫的理論和診治經驗為基本,具有科學性和可操作性。具體方法如下:

一、敲擊腳底
天天晚上臨睡前用拳頭敲擊腳底,可以打消一天的疲勞。通過敲擊給腳底以恰當的刺激,增進了全身的血液迴圈,可使內臟功效得以加強,儘快恢復精神。

準確的敲擊法是以腳掌為中心,有節奏地向四周放射進行,以稍有疼痛感為度。也可以盤腿坐在床上或椅子上,把腳放在另一側腿的膝蓋上,這樣比擬輕易敲擊。每只腳分辨敲100次左右,不可用力過度。

二、雙腳晃動
全身血液迴圈不佳,就會產生內臟失調的現象,呈現諸如頭痛、食欲不振等亞健康徵兆,簡略的腳部刺激便可增進血液迴圈。仰臥在床,先讓雙腳在空中晃動,然後像踏自行車一樣讓雙腳旋轉,只要連續56分鐘,全身血液迴圈就會得到改良,此法還可以使腿肚和膝蓋內側的肌肉得到伸展,徹底打消腿部疲勞。冬天怕冷的人假如在就寢前施行此法,就會覺得全身暖和,有助於改良睡眠。

三、赤腳行走
本方法的最大長處是使腳掌心獲得錘煉的機遇。腳掌心是堅持人體平衡的主要部位,大凡身材健康的人都具有硬朗的腳掌心。行走時盡可能讓腳心得到刺激,也可以嘗試走走卵石路,讓5個腳趾不粘在一起,能夠自由地分別和活動,是赤腳行走的一大長處,特殊是在大趾和二趾之間留有間隙,可使步履變得輕鬆起來。為了促進身體健康,在家應當盡可能讓雙腳從鞋襪中解放出來,履行赤腳行走。

四、腳底浴光
日光浴是促進身材健康的自然療法讓有第二心臟之稱的腳底接收日光浴,可以獲自得想不到的保健後果太陽中的紫外線刺激腳底,可增進全身的新陳代謝,加強內臟器官的功效,使身材硬朗起來凡是履行腳底日光浴的人,夏天不易中暑,一年四季不易感冒氣象晴好時,天天可以在室外讓陽光直接照耀腳底2030分鐘不要隔著玻璃曬太陽,由於大部分紫外線會被玻璃所接收。

五、腳底摩擦
不少患者向醫生埋怨說,他們由於心事重重或者焦躁不安,經常躺在床上睡不著覺,輾轉反側,睜著眼睛到天亮。
實在,由於腳底離心臟最遠,末梢血液迴圈不暢時,92養生網,雙腳怕冷,也輕易患失眠症。失眠時可以讓雙腳合攏起來相互摩擦,使血液迴圈暢通,待腳部覺得溫熱,便可以在短時光內酣然進睡。方式是仰臥在床上,舉起雙腳,然後用勁相互摩擦,假如雙手也同時進行摩擦則後果更好。只要用力摩擦20次,腳部就會感到暖和,睡意也就來臨了。

六、揉搓腳趾
揉搓腳趾有加強記憶力的作用。可以用手捉住雙腳的大趾做圓周揉搓運動,天天揉搓幾次,每次23分鐘。也可用手做圓周活動來揉搓小趾外側,只要在課間或睡覺前揉5分鐘就行了。由於盤算才能是與小腦相干的,而小趾又是小腦的反射區,故而揉搓小趾還有助於增強盤算才能。

七、按壓腳根
長期伏案工作或坐辦公室的人容易形成駝背,改正這種姿態的最簡略的辦法就是刺激腳後跟。背部之所以曲折,是由於支撐內臟重量的脊椎兩側的肌肉變得虛弱,只有刺激脊椎兩側的肌肉,才幹使背部挺立起來。脊椎兩側的肌肉通過膀胱經與腳後跟相連結,刺激腳後跟可以改正駝背的姿態。辦法是用手指強力按壓腳後跟,直至感到疼痛時為止。

八、單腳站立
單腳站立可以起到鍛煉腳底的作用。辦法非常簡略,就是採取金雞獨立的姿態,踮著腳尖站立。初時也許很不習慣,甚至可能感到非常苦楚,可以先讓雙腳後跟稍微分開地面一些,習慣以後再踮著雙腳的腳尖站立,最後過渡到踮著一隻腳的腳尖站立。單腳站立時,可先踮著右腳的腳尖站立12分鐘,然後再踮著左腳的腳尖站立12分鐘,重複輪流進行,踮腳時最好雙手扶牆或抓緊欄杆,切記要注意安全。

九、踮腳登樓

誕辰常生涯中,踮腳登樓是一個能使人全身得到錘煉的好機會。踮著腳尖登樓,有利於調節血壓,使人精力豐滿。與在平地上行走相比,登樓的活動量更大,可使呼吸體系、循環體系得到錘煉,腰部肌肉和腿部肌肉也得到增強,全身各項功效都有所改良。由於在全部進程中都盡可能踮著腳尖登樓,可使腳的前半部得到鍛煉,與之相干聯的內臟和大腦功能也得到必定水準的改善。踮腳登樓時思想要高度集中,小心因邁步不穩而摔倒。

十、腳踩網球
在椅子上,用腳轉動網球,當腳部覺得疲勞的時候,用網球刺激腳底,可使之得到緩解。開端轉動網球時,腳底會感到相當疼痛,假如保持一段時光後,這種疼痛感就會逐漸變為舒適感,腳部的疲勞也會在不知不覺中打消了。這種方式還有利於排除便秘。

十一、洗擦腳底

如何使皮膚白淨又細嫩,是女性最關懷的事實在,只要刺激腳底,就可以使皮膚健美。具體方法是在洗澡時用刷子摩擦腳底,通過刷子的刺激,可促進體內相干激素的分泌,天永日久,就能夠使皮膚白嫩起來,養生湯。實施這種養生方法,選用自然纖維製成的刷子即可,因為自然纖維製成的刷子比擬柔軟,不會損傷腳底。

轉貼文章 ~ 灝昇 : 牛市中的調整不要怕

首先要寫在最頭的是不論在牛市、熊市,甚至任何市況中,注碼控制永遠是投資者最重要的一點,當面對全世界go go go的歡呼聲中,保持冷靜,永遠留有一手保存實力和心態都是十分重要的,只有紙上談兵的將軍才會不停強調all in再all in。

如果手上永遠留有適量資金,當面對恒指2日間由高位下跌近1,000點,心態上應該相對較舒服的,而且從中更可能找出機會。恒指在2日前才剛創出52周新高27,876點,但在短短2日間由高位急速回落至11/8/2017收市價26,883點,急跌992點,相信這種急速的下跌會令不少投資者懷疑牛市是否會完結,不過在歷史中,原來都不乏這種創出52周新高後急跌的情況。

由2000年起至今,曾出現7次此種情況,由於以創出52周新高2個交易日內下跌多於3.5%作條件,十分嚴謹,故此7次的出現頻率是比我原先想像中多。其中一個特別之處是每次出現這種形態的日子皆是在比較大型的牛市市況中,除了2007年一次外,其餘時間都是在整體升浪的初期中出現,如2003年間的2次,2004年的一次,皆是5年大升浪的初期時間,之後的2016年9月出現形態後,雖做了3個月的調整,不過之後便是今次升浪的開端。雖然2009年較難界定是牛還是熊的市況,不過整體趨勢仍不弱。所以總體而言,這個形態是較常發生在市場牛氣漸現但信心不足之時,反映的是長遠而言市況不弱。

而較短期的走勢亦可參考出現形態之後的20日後表現,不難發現大部份情況下恒指走勢在出現這個形態後都比較偏強,排除今次,在6次形態中有5次20日後恒指收市價皆比形態出現後一個交易日開市價收得高,即是說在出現形態後的一個交易日以開市價入市,大部份情況下皆能獲利,除了2007年會有所虧損。所以整體來說,即使恒指急跌992點,仍然不用過份擔心,除非出現其他更強利淡因素,否則相信大勢依然強勁。

轉貼文章 ~ 股榮 : 炒輪完?

港股三日調整近千點,百分點約3.5%。霎時間,坊間一遍愁雲慘霧,原因不是正股重傷,乃是衍生工具出事。身邊不少朋友,近月開始嫌正股贏得唔爽,俾冧把5號仔、甚至是700,都覺得行得慢,唔夠型,取而代之,就是選擇相關股份的窩輪牛熊證(輪證)。
每次所謂大時代,港股成交飆升之時,輪證成交同樣嚇人。2007年宣布港股直通車後,窩輪每日成交皆超過300億元、最誇張的一日是10月16日的500億元成交,佔大市2,000億成交約25%。
2015年大市起動,4月開始千億成交成為新常態,連帶輪證交投創過去十年最光風的日子。統計自2008年後,近十年輪證成交逾300億元的交易日,合共有62日,當中2010年10月至11月佔7日,其餘55日清一色是2015年4月至7月發生,最多的一日是2015年5月28日,輪證成交457億元,佔大市成交約22%。
今年迄今151個交易日,輪證平均每日成交只有144億元,佔大市約19%。不過最諷刺的,是輪證成交最多的四日,就是上周二至五的四個交易日,分別錄得206億、211億、249億及215億元,佔大市成交比例同樣約兩成。
數字代表甚麼?可能有以下啟示。07及15年兩個大時代,輪證成交動輒300甚至400億元,是全民炒股炒輪炒動物的結果,上周即使錄多日逾200億元輪證成交,層次上不算全民參與,極其量是買開股票的散戶,手多多玩埋輪,或者以往炒開輪證的投資者,加大賭注而已。前者由於冇玩開,亂買末日或超級價外輪,遇上調整市,連止蝕的基本動作也欠奉,結果total loss。
以往細價股有得炒的日子,炒三四線股的朋友,絕少沾手輪證,事關風險回報相若。不過「粉塵爆」事件後,市場突然多了一班棄細炒輪的客源。炒細價股與炒窩輪,坦白講是兩碼子的事。細價股還可能靠收料、埋莊家線搵食,雖則多數聲稱收到料的,十之八九是流料。相比之下,輪證純粹賭大細,冇得鬥長命,拖得越耐越蝕章。因此,用細價股的炒法以至注碼玩輪證,五個字講晒,「輸死冇命賠」。
我仍堅信牛市未完,但當人人都知道是牛市之時、輪證成交超過300億元之日,就是搵定出口的時候。牛市贏錢,是鬥耐性,鬥EQ。想贏快錢,結果是輸得更快。想輸得型、定贏很娘,我揀後者。

 雖然手術及時救回吳先生一命,但術後他出現了心律不齊的情況,需植入除顫器。另外,吳先生現時仍會出現氣喘的情況,所以不能急步行走,每走一段路就要停下休息,而且亦不能從事粗重工作。該次經歷亦令吳先生得到教訓,他已戒煙及酒,飲食亦盡量清淡。


 事實上,糖尿病與心臟疾病有密切的關係,更會增加患者死亡率。「糖尿心」患者較多出現冠心病及心臟衰竭,前者血液流通不暢順,會引致心肌梗塞;後者則會影響心臟肌肉運作,長期可致心肌肥厚,最終亦會令心臟衰竭。



 很多糖尿病患者都著重「糖尿眼」及「糖尿腎」,卻忽視了「糖尿心」的嚴重性。其實,糖尿病患者約1015年便會開始出現併發症,「糖尿心」患者每年更可復發一至兩次,而且事前未必有明顯病徵。因此,患者的體能一旦出現下降,例如從前走34層樓梯不喘氣,但現時走不到3層便氣喘就是提高警覺,這樣可能是心肺及血管功能逐漸減弱的訊息。總括而言,糖尿病患者在管理糖尿病病情的同時,亦應注意減低心血管疾病的風險。
