Diabetic patients suddenly start shaking, break out in cold sweats, and have slurred speech — first give 15 grams of sugar, then retest after 15 minutes
糖尿病人突然发抖、出冷汗、说话不清，先给 15 克糖，15 分钟后复测
No cost involved. Just keep a few sugar cubes or a small carton of juice on hand.
First, give 15 grams of sugar — sugar cubes or a small carton of juice both work fine. Retest blood sugar levels after 15 minutes; if they’re still low, repeat the process. A blood sugar level below 3.0 mmol/L is medically significant hypoglycemia. If a person reaches a stage where they need outside help to manage it, it can be fatal. Never feed anything to someone who is unconscious — they could choke, so call emergency services right away.

The excuse
One more exception feels free because the bill arrives outside the current scene.
What feels good now
Today I keep a few minutes and avoid interrupting my default routine.
What the source says
The source summarizes the return this way: “First, give 15 grams of sugar — sugar cubes or a small carton of juice both work fine. Retest blood sugar levels after 15 minutes; if they’re still low, repeat the process. A blood sugar level below 3.0 mmol/L is medically significant hypoglycemia. If a person reaches a stage where they need outside help to manage it, it can be fatal. Never feed anything to someone who is unconscious — they could choke, so call emergency services right away.” Evidence grade A.

Original recommendation and evidence
17. Diabetic patients suddenly start shaking, break out in cold sweats, and have slurred speech — first give 15 grams of sugar, then retest after 15 minutes
Cost: No cost involved. Just keep a few sugar cubes or a small carton of juice on hand.
In plain terms: First, give 15 grams of sugar — sugar cubes or a small carton of juice both work fine. Retest blood sugar levels after 15 minutes; if they’re still low, repeat the process. A blood sugar level below 3.0 mmol/L is medically significant hypoglycemia. If a person reaches a stage where they need outside help to manage it, it can be fatal. Never feed anything to someone who is unconscious — they could choke, so call emergency services right away.
Benefit: A blood sugar level below 3.0 mmol/L qualifies as clinically meaningful hypoglycemia. If a person shows changes in consciousness or behavior that require outside assistance to manage, this is severe hypoglycemia that can be deadly.
Evidence grade: A
Sources: American Diabetes Association (2025). Standards of Care for Diabetes 2025·Chapter 6 Blood Glucose Goals and Hypoglycemia. Diabetes Care: Grading"Level 1: Glucose <70 mg/dL (<3.9 mmol/L) and ≥54 mg/dL (≥3.0 mmol/L)""Level 2: Glucose <54 mg/dL (<3.0 mmol/L)""Level 3: A severe event characterized by altered mental and/or physical status requiring assistance for treatment of hypoglycemia, irrespective of glucose level"; Treatment"For most individuals, 15 g carbohydrates should be ingested""Fifteen minutes after initial treatment, repeat the treatment if hypoglycemia persists". <https://doi.org/10.2337/dc25-S006>
Notes: Never feed anything to an unconscious person — they could choke, so call emergency services immediately. The same guidelines also recommend that people on insulin or at high risk of hypoglycemia should always carry glucagon. The original text reads: “All individuals treated with insulin or who are at high risk of hypoglycemia...should be prescribed glucagon.” Nasal glucagon sprays and pre-filled injection kits are easier to use than glucagon that needs to be mixed on the spot. This advice is aimed at you or any diabetic family members you care for — keeping sugar on hand is meant to help them in emergencies.

17. 糖尿病人突然发抖、出冷汗、说话不清，先给 15 克糖，15 分钟后复测
成本: 不花钱。随身带几块方糖或者一小盒果汁。
说人话: 先吃 15 克糖，方糖、一小盒果汁都行。15 分钟后再测一次，还低就再来一次。血糖低于 3.0 mmol/L 就是医学上要当回事的低血糖。到了要别人帮忙才能处理的程度，可以致命。意识不清的人一口都别喂，会呛进气管，直接打 120。
收益: 血糖低于 3.0 mmol/L，属于临床上有意义的低血糖。出现意识或者行动改变、需要别人帮忙处理的，是重度低血糖，可以致命
证据等级: A

备注: 意识不清的人不要喂东西，会呛进气管，直接叫 120。同一份标准还建议，打胰岛素的人、容易低血糖的人，都该备一份胰高血糖素。原文是「All individuals treated with insulin or who are at high risk of hypoglycemia...should be prescribed glucagon」。鼻喷的和事先装好药的针剂，比要临时兑药的好用。这些做法默认是给你自己或者家里的糖尿病人准备的，随身带糖也是给他们带的。
