Community Medicine Family Case History: Acute Diarrhea
Identification data
Index patient: Mr. Mehar, 50-year-old male
Occupation: Shopkeeper
Religion: Muslim
Family type: Nuclear family
Socioeconomic status: Class III, middle class, according to Modified B. G. Prasad scale 2026
Family size: Five members
Residence: Living in the same locality for approximately 20 years
The patient lives with his wife and three adult sons in a pucca house. The household uses borewell water, stores it in buckets, and does not practise water purification.
Chief complaints
Mr. Mehar presented with:
- Passage of loose stools for one day
- Colicky abdominal pain for one day
- Generalized weakness and thirst for one day
History of present illness
The patient was apparently well one day ago, after which he developed sudden onset of loose stools. He passed approximately 6-8 episodes of watery, non-bloody, non-mucoid stools over the last 24 hours. The stools were large in quantity and associated with colicky abdominal pain.
There was no history of blood or mucus in stools, high-grade fever, severe vomiting, abdominal distension, altered sensorium, or decreased urine output. He complained of weakness, thirst, and dryness of mouth. There was no history of similar illness among other family members or neighbours.
The patient gave a history of consuming food from outside, including spicy food and pickle, on the day before onset of symptoms. The family commonly consumes pickle, salted foods, and food prepared with excess salt. Household drinking water is obtained from a borewell and stored in buckets without purification, which may predispose to contamination during storage and handling.
He has not taken antibiotics or any other medication before the illness. He has taken some water at home but had not started ORS before the visit.
Negative history
There is no history of:
- Blood or mucus in stools
- Persistent vomiting
- High fever or chills
- Severe abdominal pain
- Jaundice
- Recent travel
- Consumption of suspected contaminated water outside the home
- Contact with a known case of diarrhea
- Recent antibiotic use
- Diabetes mellitus, chronic kidney disease, or chronic bowel disease
Past history
There is no past history of recurrent diarrhea, dysentery, tuberculosis, chronic liver disease, inflammatory bowel disease, diabetes mellitus, or renal disease.
There is no known history of drug allergy.
As he is being followed for hypertension risk assessment, blood pressure should be recorded before starting or modifying any treatment. During acute diarrhea, antihypertensive medication review may be required if dehydration, dizziness, or low BP develops.
Personal history
- Appetite: Reduced since onset of diarrhea
- Diet: Mixed diet
- Water source: Borewell
- Water purification: Not practised
- Water storage: Buckets
- Bowel habits before illness: Regular
- Sleep: Disturbed due to frequent stools
- Addictions: No known addiction
- Tobacco and alcohol: Denied, but should be reconfirmed
- Food habits: Frequent intake of pickle, papad, salted snacks, and high-salt food

Environmental and sanitation history
The family resides in a pucca house with three rooms, a separate kitchen, and a store room. Lighting and ventilation are adequate. LPG is used as cooking fuel.
Water
- Source: Borewell
- Quantity: Adequate
- Storage: Buckets
- Purification: Not practised
Sanitation
- Latrine: Present inside the house
- Water available in latrine: Yes
- Solid-waste disposal: Regular
- Waste-water disposal: Open drainage
Possible risk factors for diarrhea in this family
- Drinking water is not purified.
- Water stored in buckets may become contaminated if left uncovered or handled with unclean hands/cups.
- Open drainage may favour fly breeding and contamination of the household environment.
- Handwashing practices before food preparation, eating, and after defecation need to be assessed.
- Consumption of outside food and improperly stored food may be a possible precipitating factor.
Socioeconomic history
The family earns approximately ₹15,000 per month from the shop and the income of one son.
[
\text{Per-capita monthly income} = \frac{₹15,000}{5} = ₹3,000
]
The family belongs to Class III, middle socioeconomic class, according to the Modified B. G. Prasad scale, 2026.
Provisional diagnosis
Acute watery diarrhea, probably acute gastroenteritis, with no clinical features of severe dehydration at present.
The severity of dehydration must be assessed clinically by looking for thirst, dry mouth, sunken eyes, skin pinch, pulse rate, blood pressure, urine output, and mental status.
Examination to be recorded
General examination
- Temperature: ______ °F
- Pulse: ______ /minute
- Blood pressure: ______ /______ mmHg
- Respiratory rate: ______ /minute
- Hydration status: No dehydration / some dehydration / severe dehydration
- Tongue and oral mucosa: Moist / dry
- Skin pinch: Normal / slow / very slow return
- Urine output: Normal / reduced
Systemic examination
- Abdomen: Tenderness, guarding, distension, bowel sounds
- Cardiovascular system: Pulse volume, heart sounds
- Respiratory system: Normal findings / abnormal findings
- CNS: Conscious, oriented, no focal neurological deficit
Management plan
Immediate management
- Start WHO ORS in frequent small sips after every loose stool.
- Continue normal food intake. Avoid fasting.
- Give safe fluids such as boiled and cooled water, rice water, or clear soups.
- Avoid sugary soft drinks, excess tea/coffee, and very oily foods.
- Assess dehydration repeatedly.
Oral rehydration solution enhances fluid and electrolyte absorption and can reverse dehydration caused by secretory diarrhea. The mainstay of management is adequate rehydration.
WHO diarrhea guidance supports ORS and continued feeding as key measures.
Referral warning signs
Refer urgently to a health facility if there is:
- Inability to drink or persistent vomiting
- Marked thirst, lethargy, confusion, fainting, or reduced urine output
- Sunken eyes, very dry mouth, weak pulse, or low BP
- Blood in stool
- High fever
- Severe abdominal pain or abdominal distension
- Diarrhea persisting beyond 48-72 hours
- Worsening symptoms in a patient with hypertension, diabetes, kidney disease, or advanced age
Antibiotics
Antibiotics should not be started routinely for uncomplicated acute watery diarrhea. They are considered only after clinical evaluation, especially in suspected cholera, dysentery, severe infection, or specific bacterial/parasitic causes.
Health education given to the family
- Purify all drinking water by boiling, filtering, or using an appropriate household water-treatment method.
- Store water in a clean, covered, narrow-mouthed vessel.
- Use a clean ladle instead of dipping hands or cups into stored water.
- Wash hands with soap after defecation, after handling waste, before cooking, and before eating.
- Keep cooked food covered and consume it freshly prepared.
- Wash fruits and vegetables with safe water.
- Maintain cleanliness around the open drainage area and prevent fly breeding.
- Keep ORS packets available at home.
- Do not self-medicate with antibiotics or antidiarrheal drugs without medical advice.
- Continue efforts to lower salt intake, including reducing pickles, papad, added table salt, and packaged salty snacks, because of the patient’s hypertension risk.
