Low blood pressure, also known as hypotension, is usually considered a sign of good health and low risk for cardiovascular disease. However, there are times when persistently low blood pressure or a sudden drop can be a sign of an underlying health issue that needs medical attention. Knowing when low blood pressure becomes a problem can help ensure timely intervention and proper care.

Blood pressure readings consist of two numbers:

Systolic pressure (the top number) indicates the pressure in your arteries when your heart pumps blood. Diastolic pressure (the bottom number) reflects the pressure in your arteries while your heart is resting between beats.

The normal reading is usually 120/80 mmHg or less. Hypotension is clinically defined as having blood pressure readings less than 90/60 mmHg. In some patients, low blood pressure will have no adverse health consequences and therefore does not need to be treated. In extreme cases, however, it can limit the flow of oxygen and nutrients to vital organs, resulting in potentially life-threatening complications, such as shock.

Causes of Low Blood Pressure

Hypotension can result from many factors. Some of the factors that cause hypotension are as follows:

• Insufficient fluid intake or excessive fluid loss can lead to decreased blood volume and hence hypotension.
• An injury or internal bleeding may result in hypotension. This happens because blood pressure becomes significantly reduced.
• Some hormonal changes along with the increased blood requirement during pregnancy also causes hypotension.
• Issues like heart failure or arrhythmias can impair blood circulation and result in low blood pressure.
• Certain drugs, including diuretics, antidepressants, and blood-pressure-lowering medications, can induce hypotension.

Symptoms of Hypotension

While low blood pressure may not always cause symptoms, it can sometimes be associated with:

- Dizziness or fainting

- Fatigue and weakness

- Blurred vision

- Nausea

- Confusion or difficulty concentrating

- Shallow breathing

- Palpitations

If the person experiences these symptoms, with the recorded blood pressure reading, the medical services have to be consulted.

Types of Low Blood Pressure

1. Orthostatic Hypotension: This is a kind of hypotension that appears as a result of decreased blood pressure when a person is standing up from lying down or sitting position and primarily affects elderly people.

2. Postprandial Hypotension: This is a drop in blood pressure after eating, more common in older people.

3. Neurally Mediated Hypotension: It is triggered by standing for long periods. This type can affect younger people and is associated with miscommunication between the brain and heart.

When Is Low Blood Pressure Dangerous?

There is no such thing as a universal threshold for very low blood pressure, but a blood pressure reading below 90/60 mmHg can be dangerous and require prompt medical assessment if accompanied by symptoms of fainting, confusion, or shortness of breath. Sudden falls in blood pressure may point to potentially serious underlying causes, which can include:

• Internal bleeding
• Sepsis (severe infection)
• Allergic reactions

Management and Treatment

Treatment of hypotension depends on its cause:

• Hydration Drinking more water can help against dehydration-related hypotension.
• Compression Stockings: These can improve circulation and reduce blood pooling in the lower limbs.
• Dietary Changes: Increasing salt intake under supervision can help increase blood pressure
• Medication Changes: The physician may need to reduce dosages of some medications or replace prescriptions.

For more severe cases, physicians might also administer fludrocortisone or midodrine to increase blood pressure. Shock from hypotension should be treated promptly to ensure proper function of organs.

Can Hypotension Cause Fatigue?

Chronic fatigue syndrome has also been associated with low blood pressure. Prolonged tiredness, despite adequate rest, may require reassessment of blood pressure levels. Fatigue secondary to hypotension will impact functionality and thus requires assessment and treatment of the cause.

When to Seek Medical Care

If your blood pressure readings are low consistently and without symptoms, you probably have nothing to worry about. If you do have symptoms like dizziness, fainting, or confusion, you need to go to the doctor. Blood pressure checks are usually conducted regularly. Once you are aware of your own normal baseline, you will know right away when there is something wrong.

Lifestyle Tips That Support Normal Blood Pressure

1. Other than directly treating hypotension, a healthy lifestyle overall would promote balanced blood pressure levels.
2. Exercise regularly; it promotes cardiovascular health and can help regulate blood pressure.
3. Focus on nutrient-dense foods rich in iron, B vitamins, and electrolytes to support circulatory health.
4. Excessive alcohol consumption dehydrates the body and lowers blood pressure.
5. Practices like yoga and meditation can help maintain a healthy blood pressure range.

British pop star Jessie J has shared an update on her recovery after undergoing a second breast reconstruction surgery.

The 38-year-old singer-songwriter took to Instagram to share a series of photos, including one taken after her latest surgery. In the picture, she is seen wearing a hospital gown and giving a thumbs-up, with the caption, “to healing.”

The post marks Jessie’s first update since September, when she announced she would be taking a break from social media ahead of her surgery.

Jessie was diagnosed with early-stage breast cancer in 2025 and underwent a mastectomy. She announced in May 2026 that she was cancer-free.

Sharing the emotional news on Instagram, she admitted she "sobbed for hours and then exhaled for the first time in a year."

Jessie announced her diagnosis in June 2025, shortly after performing at Capital’s Summertime Ball at London’s Wembley Stadium. She spoke candidly about her diagnosis and the surgery she would undergo.

In a video message, she shared that she had been “in and out of tests” before receiving a diagnosis of early breast cancer.

“Cancer sucks in any form,” she said, adding that she was holding on to the word “early.”

Using her characteristic dark humor, she described the surgery as “a very dramatic way to get a boob job” and told her followers, “I will come back with massive boobs and more music.”

However, she also spoke openly about the emotional toll of the diagnosis, saying, “I need to process it and talk about it” and “I need a hug.”

What Is Breast Reconstruction Surgery?

Breast reconstruction surgery aims to restore the shape and contour of the breast after a mastectomy, which involves removing the entire breast. Depending on the cancer and the treatment plan, nearby skin and lymph nodes may also be removed.

Following a mastectomy, patients may choose breast reconstruction to restore breast shape and symmetry. The procedure can be performed at the same time as the mastectomy or at a later date, depending on the patient's circumstances and treatment plan.

Why Do Some Patients Need Multiple Breast Reconstruction Surgeries?

According to the American Cancer Society, breast reconstruction often involves more than one operation. The number and type of procedures depend on the reconstruction method, the patient's needs and the desired outcome.

There are two main types of breast reconstruction:

• Implant reconstruction: A saline or silicone implant is used to rebuild the breast.
• Tissue flap reconstruction: Tissue taken from another part of the body is used to reconstruct the breast.

In some cases, surgeons combine the two approaches.

Reconstruction may be immediate, taking place during breast cancer surgery, or delayed until a later date. Both implant-based and tissue flap reconstruction can be performed using either approach.

After the initial reconstruction, some patients may undergo additional procedures to refine the breast's appearance or feel. These may include fat grafting, scar revision or procedures to recreate the nipple and areola, sometimes using medical tattooing.

Benefits And Risks Of Breast Reconstruction

Breast reconstruction can help restore breast shape and symmetry after a mastectomy. For some patients, it may also improve body image, confidence and emotional well-being. However, the benefits vary from person to person.

As with other surgical procedures, breast reconstruction carries potential risks and complications, including:

• Infection
• Fluid or blood accumulation
• Delayed wound healing
• Changes in sensation
• Implant-related complications
• Capsular contracture
• Blood clots, including deep vein thrombosis and pulmonary embolism
• Psychological effects.

Low-dose naltrexone has received plenty of attention as a strong candidate for treating people with chronic fatigue after COVID-19. But a new randomised clinical trial has found no significant improvement in fatigue, pain or any other symptoms when compared to a placebo.

The study, posted on medRxiv, examined low-dose naltrexone (LDN) in adults with post-COVID fatigue syndrome. The findings challenge hopes that an existing repurposed drug could provide relief for people whose symptoms have not subsided months after infection.

The paper has not yet undergone peer review, which means its findings have not been independently evaluated in a formal manner.

Study Based On 160 Adults With Long COVID

160 adults aged 19 to 69 from British Columbia and Ontario, Canada participated in the trial. Participants had developed symptoms that resembled myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS) after a SARS-CoV-2 infection.

Researchers randomly assigned participants either low-dose naltrexone or a placebo for 16 weeks. The naltrexone dose began at 1 milligram daily and increased to a maximum of 4.5 milligrams, depending on how participants tolerated the treatment.

The main outcome was fatigue severity, which was measured using the Fatigue Severity Scale. At the end of the study, the average fatigue score was 4.2 in the LDN group and 4.4 in the placebo group.

The difference between the groups was not statistically significant, meaning the trial proved that the drug did not improve fatigue.

Researchers also found no significant differences between the groups in pain, overall ME/CFS symptoms, daily step counts or any other health aspects related to quality of life.

These results suggest that LDN did not provide any measurable benefit for the participants. The study also found that LDN was generally well tolerated over the 16-week period.

However, adverse events classified as grade 3 or higher were reported in five participants in the LDN group, or 6.2%, compared with three participants in the placebo group or 3.8%.

Naltrexone is an established medicine used at standard doses to treat alcohol use disorder and opioid use disorder. At much lower doses, it has been tested for conditions involving chronic pain, inflammation and fatigue.

LDN’s effects on immune signalling and inflammatory conditions have sparked interest in its potential use for long COVID, a condition that can involve fatigue, cognitive difficulties, pain, breathlessness and symptoms affecting several biological functions.

Researchers Caution

The findings apply specifically to adults with post-COVID fatigue syndrome who met the study’s criteria for ME/CFS-like symptoms.

Long COVID refers to symptoms that occur after a SARS-CoV-2 infection and cannot be explained by another diagnosis. Symptoms vary widely and may include fatigue, cognitive difficulties, breathlessness, sleep disturbances and problems with everyday activities.

Some people improve over time, while others experience prolonged illness that affects their ability to lead routine lives.

The results do not mean that long COVID symptoms are untreatable. Instead, they highlight how difficult it can be to identify effective treatments for a condition with varied symptoms.

There are currently no FDA-approved medicines specifically for long COVID, and care often focuses on managing individual symptoms.

People taking or considering naltrexone should discuss its benefits and risks with a healthcare professional rather than starting or changing treatment on their own.

Low-dose aspirin could play a key role in lowering the risk of dementia significantly in some older adults, according to a new genetic analysis. However, the benefit does not come without a complication: major bleeding.

The study, led by researchers at Monash University in Australia, is based on data from more than 13,500 participants in the ASPREE trial, which investigated the effects of low-dose aspirin in older adults. The study was published in Alzheimer’s & Dementia: The Journal of the Alzheimer’s Association.

Researchers found that the benefit was mostly seen among people with a specific genetic trait linked with platelet count.

Platelets are small blood components that help form clots and stop bleeding. Researchers have previously examined how aggregation of platelets might contribute to dementia, but the role of genetically influenced platelet counts still remains unclear.

The researchers examined genetic scores related to platelet count and compared dementia results among participants who were either assigned aspirin or placebo.

Among people in the highest 20% of platelet count genetic scores, dementia developed in 1% of those taking aspirin, compared with 3.3% of those receiving a placebo. This represented approximately a 70% lower risk.

Lead author Dr Peter Fransquet, a research fellow at Monash University's School of Public Health and Preventive Medicine, said, “Previous trials found aspirin didn't prevent dementia when everyone was considered together.”

“Our findings suggest there may be more to the story,” he said.

Risk Of Bleeding Increased

The benefit was accompanied by a safety concern. Among participants in the same genetic subgroup, major bleeding occurred in 4.4% of those assigned to aspirin, compared to 2.1% of those given a placebo. That is a difference of 2.3 percentage points in both dementia cases and major bleeding events. In other words, the lower dementia rate cannot be considered in isolation from the increased bleeding risk.

Aspirin reduces the ability of platelets to form clots. This can be useful for certain people who need to take precaution against cardiovascular events, but it can also increase the risk of serious bleeding, including bleeding in the gastrointestinal tract or brain.

The study therefore does not prove that aspirin offers a favourable overall balance of benefits and harms for people with this genetic profile.

Could This Help Personalise Dementia Prevention?

The researchers found that the genetic signal was not linked to established genetic risk factors for Alzheimer's disease and dementia. Instead, it pointed towards platelet factor as a possible direction for further research.

“What's particularly interesting is that the signal wasn't linked to the established genetic risk factors for Alzheimer's disease and dementia,” Fransquet said. “Instead, it's pointing us towards platelet biology and gives us a new avenue to investigate.”

The findings could contribute to more personalised approaches to dementia prevention, in which treatments are tailored to characteristics that influence how individuals respond. But the results need to be replicated in other populations and tested in a clinical trial specifically designed for people with the identified genetic profile.

Fransquet said, “People shouldn’t start taking aspirin to prevent dementia on the basis of this study without consulting with their doctor, particularly given the increased risk of serious bleeding,” he said.
