Here is a clear, practical guide covering both the immediate first-aid steps and what happens in hospital.
Bleeding in the Head - What To Do
This covers two scenarios: external scalp bleeding (a wound on the outside of the head) and internal brain bleeding (intracranial hemorrhage), which is a stroke-level emergency.
Part 1 - Immediate First Aid (Before Help Arrives)
Step 1: Call Emergency Services NOW
- Dial 911 (US), 999 (UK), 112 (EU), or your local emergency number immediately.
- Brain bleeding is time-critical. Every minute without treatment risks more brain damage.
Step 2: Recognize Warning Signs of Internal Head Bleeding
Look for any of these:
- Sudden, severe headache ("worst headache of my life")
- Confusion, slurred speech, or inability to speak
- Weakness or numbness on one side of the body or face
- Vision problems
- Loss of consciousness or unresponsiveness
- Seizures
- Unequal pupils
- Vomiting repeatedly
Step 3: What To Do While Waiting for Help
If she is conscious:
- Keep her as still and calm as possible
- Lay her down with her head and shoulders slightly raised (about 30 degrees) - this helps reduce pressure in the skull
- Do NOT give her food, water, aspirin, or any pain medication (aspirin and NSAIDs thin the blood)
- Do NOT let her sleep without being monitored - you need to watch for worsening
If she is unconscious but breathing:
- Place her in the recovery position (on her side) to keep the airway open and prevent choking if she vomits
- Monitor her breathing constantly
If she has stopped breathing:
- Begin CPR immediately
For external scalp wounds:
- Apply firm, gentle pressure with a clean cloth or bandage
- Do NOT press hard on a wound if you suspect the skull is fractured underneath
- Do NOT remove any object (glass, metal) stuck in the head - stabilize it and let paramedics remove it
- Scalp wounds bleed a lot even when minor, because the scalp has a rich blood supply
Part 2 - What NOT to Do
| Do NOT | Why |
|---|---|
| Give aspirin or ibuprofen | They thin the blood and worsen bleeding |
| Remove lodged objects | Can cause more damage and increase blood loss |
| Leave her alone | Condition can deteriorate rapidly |
| Let her "sleep it off" | Loss of consciousness may be a sign of worsening bleed |
| Shake or move her suddenly | Risk of spinal injury alongside head injury |
Part 3 - Hospital Treatment (What Doctors Do)
Once in hospital, management focuses on:
1. Stabilize Airway, Breathing, Circulation (ABCs)
- Patients may need intubation and mechanical ventilation if unconscious
- Oxygen is given to prevent secondary brain injury
2. Control Blood Pressure
- For spontaneous brain bleeds: blood pressure is carefully lowered to a systolic target of around 140 mmHg within the first hour, using IV medications like nicardipine or labetalol
- Rapid or extreme drops in BP are avoided as they can worsen outcomes
3. Reverse Anticoagulation (if applicable)
- If the patient is on warfarin, dabigatran, or other blood thinners, these must be reversed urgently
- Vitamin K, fresh frozen plasma (FFP), or specific reversal agents (e.g., idarucizumab for dabigatran) are used
4. Reduce Intracranial Pressure (ICP)
- Head of bed elevated to 30 degrees
- IV mannitol or hypertonic saline may be given
- Hypotonic fluids are avoided
5. Prevent and Treat Seizures
- Anti-epileptic medications may be given, especially for bleeds near the brain surface
6. Imaging
- CT scan is done urgently to identify the type and location of bleed
- Types include: epidural, subdural, subarachnoid, and intracerebral hemorrhage - each has a different prognosis and treatment
7. Neurosurgery
- Surgery (craniotomy or burr holes) may be needed to drain a large hematoma, clip a ruptured aneurysm, or relieve pressure
Summary - Priority Order
- Call emergency services immediately
- Keep her still and monitor breathing
- Recovery position if unconscious and breathing
- CPR if not breathing
- Apply gentle pressure to external wounds only (not if skull fracture suspected)
- No food, water, or blood-thinning medications
- Get to hospital fast - outcomes are dramatically better with rapid treatment

normal blood pressure levels 2025 guidelines AHA ACC
Here is a clear breakdown of blood pressure levels, based on the latest AHA/ACC guidelines (updated August 2025):
Normal Blood Pressure Levels
What Do the Numbers Mean?
Blood pressure is written as two numbers, like 120/80 mmHg:
- Top number (Systolic) - the pressure in your arteries when your heart beats and pumps blood out
- Bottom number (Diastolic) - the pressure in your arteries when your heart is resting between beats
Blood Pressure Categories (AHA/ACC 2025 Guidelines)
| Category | Systolic (mmHg) | Diastolic (mmHg) | |
|---|---|---|---|
| Normal | Less than 120 | and | Less than 80 |
| Elevated | 120 - 129 | and | Less than 80 |
| Stage 1 Hypertension (High BP) | 130 - 139 | or | 80 - 89 |
| Stage 2 Hypertension (High BP) | 140 or higher | or | 90 or higher |
| Hypertensive Crisis (Emergency) | Higher than 180 | and/or | Higher than 120 |
Source: Harrison's Principles of Internal Medicine, Table 288-1 (ACC/AHA Classification) + 2025 AHA/ACC guidelines
What is Low Blood Pressure?
Blood pressure below 90/60 mmHg is generally considered low (hypotension). Symptoms include dizziness, fainting, and weakness.
Key Points to Remember
- Normal = below 120/80 mmHg - this is the ideal target for healthy adults
- Elevated (120-129/below 80) - not yet hypertension, but a warning sign - lifestyle changes are recommended
- Hypertension starts at 130/80 - per 2017 and 2025 AHA/ACC guidelines, this is when cardiovascular risk rises significantly
- Treatment is now recommended sooner - the 2025 guidelines lower the treatment threshold from 140 to 130 mmHg systolic, especially for people with diabetes or kidney disease
- A single high reading does not confirm hypertension - doctors average two or more readings on two or more visits
How to Keep BP in the Normal Range
- Reduce salt (sodium) intake
- Exercise regularly (at least 30 minutes most days)
- Maintain a healthy weight
- Avoid smoking and limit alcohol
- Manage stress
- Sleep 7-8 hours per night
Special Populations
| Group | Notes |
|---|---|
| Children under 13 | Normal is based on age, sex, and height - different tables apply |
| Pregnant women | BP above 140/90 during pregnancy signals preeclampsia - requires urgent care |
| Elderly | Slightly higher readings may be accepted in very old patients depending on frailty |
| Diabetes / Kidney disease | Treatment should start at 130 mmHg per 2025 guidelines |
If you are unsure about your readings, a doctor or pharmacist can help you interpret them properly.

Here is a thorough, evidence-based answer drawn from Harrison's, Robbins' Pathology, Lippincott Pharmacology, and the latest AHA/ACC guidelines:
High Blood Pressure (Hypertension) - Causes and How to Lower It
Part 1: What Causes High Blood Pressure?
There are two main types:
1. Primary (Essential) Hypertension - 90-95% of all cases
This is the most common type and has no single identifiable cause. It develops from a combination of:
| Risk Factor | Details |
|---|---|
| Genetics / Family history | Having a parent with hypertension significantly raises your risk |
| High salt (sodium) intake | Sodium causes the body to retain water, raising blood volume and pressure |
| Obesity / overweight | Extra weight forces the heart to work harder; nearly 75% of US adults are overweight |
| Physical inactivity | Lack of exercise weakens the heart and raises BP |
| Age | BP naturally rises with age as arteries stiffen |
| Alcohol | Regular alcohol consumption is directly linked to higher BP |
| Stress | Chronic stress activates the nervous system, raising BP |
| Smoking | Damages blood vessel walls and causes them to narrow |
| Sleep apnea | Low oxygen during sleep triggers hormonal changes that raise BP |
| Poor diet | Low potassium, low fiber, high saturated fat diets all contribute |
| Race | Black individuals are at higher risk and often develop hypertension earlier |
2. Secondary Hypertension - 5-10% of cases
This type has an identifiable, treatable underlying cause, including:
- Kidney problems - chronic kidney disease, renal artery stenosis, glomerulonephritis, polycystic kidneys
- Adrenal gland disorders - primary aldosteronism, Cushing syndrome, pheochromocytoma
- Thyroid disease - hyperthyroidism (overactive thyroid)
- Hormonal medications - oral contraceptives, steroids, some decongestants
- Coarctation of the aorta (narrowing of the main artery from the heart)
- Pregnancy (preeclampsia)

Part 2: How to Lower Blood Pressure
A. Lifestyle Changes (First-Line for Everyone)
These are proven, evidence-based interventions with specific expected BP reductions:
| Intervention | What to Do | Expected BP Reduction |
|---|---|---|
| DASH Diet | Eat fruits, vegetables, whole grains, low-fat dairy; limit saturated fat and red meat | ~5 mmHg systolic |
| Reduce salt | Keep sodium below 2,300 mg/day (ideally 1,500 mg/day); avoid processed foods | ~5 mmHg systolic |
| Lose weight | For every 1 kg (2.2 lb) lost, BP drops by about 1 mmHg | ~1 mmHg per kg lost |
| Exercise regularly | 150 minutes of aerobic exercise per week (brisk walking, swimming, cycling) | ~5-7 mmHg systolic |
| Increase potassium | Eat bananas, sweet potatoes, spinach, beans (unless you have kidney disease) | ~3 mmHg systolic |
| Reduce alcohol | No more than 1 drink/day for women, 2/day for men | ~3-4 mmHg systolic |
| Quit smoking | Smoking immediately raises BP and damages arteries long-term | Significant |
| Manage stress | Meditation, breathing exercises, adequate sleep (7-8 hours) | Variable |
Source: Harrison's Principles of Internal Medicine 22E (2025), Table 288-Part 38
The combined effect of all lifestyle changes together can lower systolic BP by 10-20 mmHg - enough to eliminate the need for medication in many Stage 1 hypertension patients.
B. Medications (When Lifestyle Changes Are Not Enough)
Doctors prescribe medication when BP remains above 130/80 mmHg despite lifestyle changes, or immediately for Stage 2 hypertension (140/90+). The main first-line drug classes are:
| Drug Class | Examples | Notes |
|---|---|---|
| Thiazide diuretics | Hydrochlorothiazide, chlorthalidone | Remove excess salt and water; often first choice |
| ACE inhibitors | Lisinopril, enalapril | Relax blood vessels; preferred in diabetes/kidney disease |
| ARBs | Losartan, valsartan | Similar to ACE inhibitors; used if ACE causes a cough |
| Calcium channel blockers | Amlodipine, nifedipine | Relax and widen arteries; preferred in Black patients and the elderly |
| Beta-blockers | Metoprolol, atenolol | Slow the heart; preferred if heart disease is also present |
Key point: For Black patients, thiazide diuretics or calcium channel blockers are preferred as first-line choices. For patients with kidney disease (CKD), ACE inhibitors or ARBs are preferred because they also protect the kidneys.

Part 3: Danger Signs - When to See a Doctor Urgently
Go to the emergency room if BP is above 180/120 mmHg, especially with:
- Chest pain or shortness of breath
- Severe headache or blurred vision
- Nausea or confusion
- This is a hypertensive crisis and requires immediate treatment
Summary
- Most hypertension (90-95%) has no single cause - it builds up over years from genetics, diet, lifestyle, and age
- Lifestyle changes work - cutting salt, losing weight, exercising, and the DASH diet can each lower BP by 3-7 mmHg
- Medication is safe and effective when needed - there are several good options tailored to each person
- Getting checked regularly matters - hypertension has no symptoms until it causes heart attack, stroke, or kidney damage
