Diarrhoea, a high glucose reading, and a lost day of wages
Ramesh, a 52-year-old daily-wage labourer, walks 8 km to your HWC in Unnao with three days of watery diarrhoea and weakness. He has no fever, no blood in stool, and is able to drink. While registering him, the ASHA notes he smokes bidis daily and has a BMI of 27. A glucometer reading taken because he is over 30 is 236 mg/dL random. His BP is 146/92 mmHg on one reading. He has no known diabetes or hypertension and no polyuria, polydipsia or weight loss. His father had diabetes and died after a stroke. Ramesh wants ORS and says he must return to work by noon or lose a day's wages. The HWC has ORS, no insulin, and can send samples to the CHC laboratory. The OPD has 40 patients waiting and one ANM is doing immunization.
1. What is your immediate clinical priority, and how would you assess and treat Ramesh's diarrhoea without being distracted by the glucose reading?

The immediate priority is to assess and treat dehydration from acute diarrhoea. I would ask about vomiting, urine output, and ability to drink, and look for sunken eyes, dry mouth, skin pinch, and weakness. He is able to drink and has no blood in stool, so this is likely acute watery diarrhoea without dysentery. If there are no signs of severe dehydration, I would give ORS and explain how to take it after each loose stool, continue food, and return if there is blood, persistent vomiting, reduced urine, or worsening weakness.
I would not start antibiotics routinely for acute watery diarrhoea. I would not withhold ORS because of the high glucose reading. The glucose result is important but it does not change the immediate need for rehydration.
Because he has to return to work, I would give a clear ORS demonstration and a take-home supply, and ask the ASHA to follow up. If he has severe dehydration, persistent vomiting, or cannot drink, I would refer immediately for intravenous fluids. The reasoning is that deaths from diarrhoea are usually from dehydration, not from a single high glucose reading, and the acute problem must be stabilised first.
2. Does the random glucose of 236 mg/dL confirm diabetes? What would you do about the glucose and BP findings at this visit?
Read the worked answer
A single random glucometer reading of 236 mg/dL does not confirm diabetes in a person without classic symptoms. A random plasma glucose of 200 mg/dL or more is diagnostic only when there are classic symptoms such as polyuria, polydipsia, and unexplained weight loss, or when it is confirmed by a second test. Ramesh has no such symptoms, and a glucometer is a screening device, not a laboratory confirmation.
My action would be to arrange confirmation: fasting plasma glucose, a 2-hour oral glucose tolerance test, or HbA1c at the CHC laboratory, as per the national NCD protocol. I would explain that the reading is high and needs checking, but I would not label him as diabetic or start medication today. Starting insulin or an oral drug without confirmation could harm him, especially when he is dehydrated and has not eaten properly.
For BP, one reading of 146/92 is not enough. I would repeat it after rest on two occasions. If it remains high, I would follow the hypertension protocol, including lifestyle advice and confirmation.
I would also use this visit to do a brief risk assessment: tobacco use, family history of diabetes and stroke, BMI 27, and age above 30. These justify follow-up even if today's tests are not diagnostic.
3. How would you organise follow-up so that Ramesh does not lose another day's wages, and what role would the ASHA play?
Read the worked answer
I would recognise that a daily-wage worker will not return for a routine appointment that costs him a day's income. So I would make the follow-up as concrete and low-cost as possible:
- Give him a written slip with the date and time for a fasting blood sample, preferably early morning so he can still reach work.
- Ask the ASHA to remind him two days before and to tell him that the test is free at the HWC or CHC.
- Combine the fasting glucose, BP repeat, and tobacco cessation advice into one visit rather than asking him to come repeatedly.
- Explain the warning symptoms of diabetes and hypertension in simple terms, and tell him to return earlier if they occur.
- Offer tobacco cessation counselling now, because he smokes bidis daily and has a family history of stroke. I would not simply say 'stop smoking'; I would ask what would help and link him to the National Tobacco Control Programme cessation support if available.
The ASHA's role is not to diagnose but to support access: remind him, accompany him if needed, and report whether he attended. I would record the plan in his card and the HWC NCD register. The reasoning is that screening is only useful if confirmation and follow-up actually happen, and for a poor patient the practical barriers matter as much as the clinical advice.
