Three of the most common reasons people in Guwahati look for a doctor are not major illnesses. They are fever, a cough that will not settle, and acidity. And for exactly that reason, most people are unsure whether to bother anyone at all.
The short answer on when to see a doctor for fever, cough, or acidity: for mild, short-lived symptoms with no warning signs, an online consultation is usually enough, and often all you need. Once a fever passes after 48 to 72 hours, a cough passes after two weeks, or acidity stops responding to basic treatment, you have crossed into territory that needs proper examination and, frequently, a lab test.
This is not about diagnosing yourself. It is about knowing which of your everyday symptoms a doctor can settle in ten minutes, and which ones need a test before anyone can honestly tell you what is going on.
When to see a doctor for fever: the day-by-day rule
Most fevers here, especially through the monsoon months, are viral and settle on their own within a few days with rest, fluids, and basic fever management.
A consultation is usually enough when the fever is mild to moderate, has lasted under 48 hours, and comes with none of the warning signs below. A doctor can guide you on managing it at home and tell you exactly when to reassess.
You need an examination and likely a blood test when:
- The fever has lasted more than 48 to 72 hours without improving.
- It is a high fever, above 101°F in an adult, or any fever in an infant under three months.
- It comes with a rash, a stiff neck, confusion, or repeated vomiting.
- There is abdominal pain or tenderness, unusual lethargy or restlessness, or any minor bleeding, which the Government of India’s National Guidelines for Clinical Management of Dengue Fever list as warning signs requiring prompt assessment.
- There is bleeding from the nose or gums, or blood in the stool.
This matters more in Assam than in many parts of India. Fevers here are not always simple viral ones. Dengue, malaria and other vector-borne illnesses are genuinely common during and after the monsoon, and they cannot be told apart from an ordinary viral fever by symptoms alone. They need a blood test.
Timing matters too. The NS1 antigen test for dengue is most accurate between days 1 and 5 of fever, while antibody testing becomes useful from around day 5 onwards. This is precisely why a consultation on day three is more useful than waiting until day six: the doctor can order the right test at the right time, rather than ordering a test that is too late.
When to see a doctor for a cough that will not settle?
A short cough after a cold feels too minor to bother a doctor with. Usually that instinct is correct.
A consultation is usually enough when the cough is dry or mild, has lasted under two weeks, and is gradually improving rather than worsening.
You need examination and likely a test when:
- The cough has lasted more than two to three weeks, particularly if it is getting worse.
- It is producing discoloured phlegm, yellow, green or blood-tinged
- It comes with breathing difficulty, chest pain, or a fever that will not settle.
- It improves and then returns worse, a pattern that can suggest a secondary infection.
There is a specific Indian reason the two-week mark carries more weight here than in Western health advice. According to the WHO Global Tuberculosis Report 2025, India accounts for roughly 25% of the world’s TB cases, with an incidence rate of 187 per lakh population. A cough lasting beyond two weeks is TB’s most commonly reported first symptom, and because TB develops slowly, it is very often mistaken for a cold that simply will not go away.
That is, the cough should not be managed indefinitely at home. A test either rules it out or catches it early, and both outcomes are worth ten minutes of a doctor’s time.
When to see a doctor for acidity?
Acidity is among the most self-treated complaints in India, frequently for far longer than is wise.
A consultation is usually enough when the discomfort is occasional, clearly linked to specific foods or meal timing, and responds to standard antacid measures.
You need examination and likely a test when:
- The discomfort is severe, persistent, or worsening despite standard treatment.
- There is difficulty or pain when swallowing.
- You notice unintentional weight loss alongside the digestive symptoms.
- There is vomiting of blood, or black or tarry stools, which needs urgent assessment rather than home management.
- You have been self-treating with over-the-counter antacids for weeks without genuine improvement.
Persistent acidity that does not respond to basic treatment is not something to keep managing on your own indefinitely. It is exactly the pattern that deserves a proper look before it gets written off as “just acidity.”
The warning signs that apply to all three
Some symptoms mean the same thing regardless of which complaint you started with. They mean stop managing this at home.
| Warning sign | What it can indicate |
| Difficulty breathing, chest pain, or bluish lips | Emergency; go to hospital now |
| Confusion, seizures, or a stiff neck | Emergency; go to hospital now |
| Repeated vomiting or inability to keep fluids down | Dehydration risk; needs prompt assessment |
| Bleeding from gums or nose, in vomit, or in stool | Urgent assessment, not home treatment |
| Symptoms beyond the usual window: fever over 3 days, cough over 2 weeks | Needs examination and likely a test |

Why is a consultation worth it even when nothing is wrong?
The hardest part of fever, cough, or acidity is rarely the illness. It is the uncertainty. Is this normal, or should I be worried? Can I wait it out, or am I making a mistake?
A consultation resolves exactly that, without a half-day at a hospital to find out your fever was a simple viral one after all. A doctor listens, asks the questions that matter, and tells you plainly whether this is manageable at home or needs a closer look. If a test is needed, it gets arranged at the right point in the illness rather than too early or too late.
At Uzuhealth, that decision does not rest on you alone either. A Health Counselor listens to what is actually happening before anything is booked, so you are matched to the right kind of care: a quick consultation, a lab test, or an in-person examination if that is genuinely what your symptoms call for.

Ask rather than guess
Fever, cough, and acidity are common enough that it is tempting either to ignore them completely or to assume the worst. Neither is necessary. Most of the time, a short consultation is all it takes to know which one you are dealing with, and if something more is needed, you will know that too instead of wondering.

1. When should you see a doctor for fever?
See a doctor if a fever lasts more than 48 to 72 hours without improving, goes above 101°F in an adult, occurs at all in an infant under three months, or comes with a rash, stiff neck, confusion, repeated vomiting, abdominal pain, or any bleeding. Milder short-lived fevers can usually be assessed and managed through a consultation.
2. When to see a doctor for a cough?
A cough lasting more than two to three weeks, worsening over time, producing discoloured or blood-tinged phlegm, or accompanied by breathing difficulty or chest pain needs proper evaluation. In India, a cough beyond two weeks is also the most common first symptom of TB, which makes early assessment particularly important.
3. How many days of fever is serious in Guwahati?
Beyond 48 to 72 hours without improvement, a fever should be assessed rather than managed at home, especially during and after the monsoon when dengue and malaria are common in Assam. These cannot be distinguished from ordinary viral fever by symptoms alone and require a blood test.
4. What are the dengue warning signs I should watch for?
The Government of India’s national dengue guidelines list recurrent vomiting, abdominal pain or tenderness, unusual weakness, lethargy or restlessness, and minor bleeding as warning signs that require prompt medical assessment.
5. When is acidity a sign of something more serious?
If acidity is severe, persists despite antacids, or comes with difficulty swallowing, unintentional weight loss, or any sign of bleeding such as vomiting blood or black stools, it needs prompt evaluation rather than continued self-treatment.
6. Can a doctor order a test through an online consultation?
Yes. If your symptoms suggest a test is needed, the doctor can advise and arrange the appropriate lab work, which also helps ensure the test is done at the right stage of the illness rather than too early or too late.
