Herbal medication, food supplements can cause serotonin syndrome
However, often we are unaware that too much serotonin causes serotonin syndrome, with symptoms that can range from mild to severe. If the condition is not identified and treated, it can be life-threatening. If it is identified, it can be easily treated and cured.
"Serotonin syndrome is a condition that occurs when the serotonin levels are high in the body. It can happen following the consumption of medicines which contain serotonin, like some antidepressants, painkillers, etc. It can also happen following the consumption of some herbal medications and food supplements," said Dr Arun B Nair, professor of psychiatry at Government Medical College, Thiruvananthapuram.
According to Dr TR John, senior consultant in psychiatry at Aster Medcity, Kochi, single medicines or chemicals do not usually cause serotonin syndrome unless the person is genetically vulnerable. Antidepressants, antimigraine medications, drugs of abuse, opioids, nutraceuticals, etc. can cause serotonin syndrome. Thus, the patient should communicate with the doctor if he or she is taking any other medicines," he said.
The initial symptoms of serotonin syndrome include a feeling of nervousness; some abdominal discomfort, which includes nausea, diarrhoea, tremors of the body parts, vomiting, and dilated pupils.
"But as the condition advances and becomes moderate, there will be a feeling of restlessness, anxiety, a subjective sense of agitation, and problems with muscles and involuntary contractions. In severe cases, muscles will also be rigid. There will be profuse sweating and shivering. There will be abnormal movements of the eyes," added Dr Arun.
In severe stages, there can be disorientation, altered consciousness, and an increase in heart rate, body temperature, and blood pressure.
"There can be fainting episodes, sudden falls, and rarely, seizures. Usually, it is a very rare condition, but it can happen in a few hours when a person is taking medicine or food supplement which contain serotonin. Usually, the reason is the consumption of more than one medicine which has serotonin content or more than one medicine which increases the serotonin levels," Dr Arun said.
"Awareness about the symptoms, which usually involves nervousness, discomfort, nausea, diarrhoea, and tremors, can help. If there is a history or family vulnerability, notice agitation, anxiety, and other early symptoms and seek help from a healthcare provider," Dr John said. He added that the syndrome can be caused when we change medicine, start a new medicine, change the dosage, or add a second medicine. Substance abuse, while on medications, can also cause Serotonin Syndrome.
Early identification and treatment are crucial in curing the condition. "In mild cases, stop taking the drug, which is likely to produce serotonin. Usually, within one to three days, the symptoms will completely go away. In moderate cases, it is better to observe the patient at the hospital for 24 hours. In severe cases, the patient will have to be placed in the ICU. Certain medications and IV fluids are used to improve the heart rate and blood pressure," Dr Arun added.
"We need to be careful about moderate and severe cases. In these cases, hospitalisation is required. In severe cases, the patient will need ICU care and can develop long-term complications if not treated aggressively. Medications, IV fluids, and supportive care should be given in such cases," added Dr John.

Herbal medication, food supplements can cause serotonin syndrome
Humans need to produce serotonin since it has an impact on both the body and the brain. A neurotransmitter and hormone, serotonin is crucial for blood clotting, digestion, mood management, sleep, and overall well-being. However, often we are unaware that too much serotonin causes serotonin syndrome, with symptoms that can range from mild to severe. If the condition is not identified and treated, it can be life-threatening. If it is identified, it can be easily treated and cured.

In the early stage, most breast cancers are painless
Myth: Breast cancer only affects middle-aged or older women Fact: Postmenopausal ladies are at more risk of developing breast cancer. However, we are seeing an increase in the number of young women in their 30s and40s also developing an aggressive breast cancer variant called triple negative type. Myth: One will develop breast cancer only if there is family history Fact: Majority of breast cancer occurs in those without any family history. Risk increases in those whose first degree relatives (mother, siblings, children) develop breast cancer, particularly at a young age. Genetic predisposition like BRCA also increases risk, although it's rare, less than a percentage. Myth: Breast pain is the symptoms of breast cancer Fact: In the early stage, most breast cancers are painless. Only once they grow and invade surrounding muscles or nerves do they cause pain. Myth: Breast lumps are breast cancers Fact: In young women, hormonal changes can lead to development of fibrocystic disease, which is common and not cancerous. In such lumps they feel engorgement and pain during some days of the menstrual cycle. An ultrasound will help to differentiate these lumps from cancer. Myth: Men do not get breast cancer Fact: One per cent of all breast cancers occur in men. Unfortunately they are more aggressive than those in women, as they come at a late stage. Irrespective of gender, a persistent, growing swelling needs evaluation. (Dr Arun Warrier is a senior consultant, medical oncologist, Aster Medcity)

Kerala Nipah virus: After death in Malappuram, patient critical in Palakkad; officials on alert
The condition of a Nipah virus-infected patient reported in north Kerala's Palakkad continued to remain critical, with state health minister Veena George saying that all possible treatment is being provided. A three-kilometre radius around the patient's house has been declared a containment zone,(PTI) The 38-year-old woman, a native of Thachanattukara, is undergoing treatment at the Government Medical College in Kozhikode, news agency PTI reported. Concerns over the woman's critical condition were raised as a Malappuram native succumbed to the virus last week. The health minister said that the woman has been given monoclonal antibody treatment according to the protocol, with the second dose administered on Monday morning. "This is the first Nipah case reported in Palakkad. The patient's condition remains critical, but all available treatment is being provided," the minister told reporters after the meeting. George said that a total of 173 contacts related to the woman have been identified, of whom 100 were primary and 73 secondary. Among them 52 are considered high-risk and 48 are low-risk, she added. ALSO READ | Two suspected Nipah virus cases flagged Kerala, three districts on alert Five samples have tested negative so far, and four more will be tested at the Manjeri Medical College on Monday. Meanwhile, a three-kilometre radius around the patient's house has been declared a containment zone, with strict surveillance being carried out by the district police chief and district collector. After chairing a high-level review meeting at the Palakkad Medical College, which was also attended by the district collector, police chief, and senior health officials, the minister warned of strict action against those spreading false information related to the virus outbreak. On Saturday, the death of an 18-year-old girl was confirmed to have Nipah infection. The patient from Malappuram's Chettiyarangadi succumbed after receiving treatment at a private hospital in Kozhikode. Initial tests suggested Nipah and the infection was subsequently confirmed by Pune's National Institute of Virology (NIV). According to the World Health Organisation (WHO), Nipah virus infection is a zoonotic illness that is transmitted from animals to people, and can also be transmitted through contaminated food or directly from one person to another. The virus causes a range of illnesses in infected people, from asymptomatic infection to acute respiratory illness and fatal encephalitis. Nipah can also cause severe disease in animals such as pigs, resulting in significant economic losses for farmers.
