Can IV Fluids Save My Elderly Mother-in-Law's Life? - Family Medicine

Share to:

Intravenous saline solution


My mother-in-law is 70 years old and is refusing to eat due to a disability and possible feelings of hopelessness.
She is not accepting any advice or encouragement.
We have already taken her to the hospital for IV fluids.
If she continues to refuse food, can IV fluids sustain her life? Is there a risk that she could lose her life because of this? How long can she survive on IV fluids alone? Besides IV fluids, what other methods does the hospital have to help her? I'm very anxious and thank you.

Please first understand the underlying issue; if necessary, you may consult a psychiatrist.
IV saline is only a temporary treatment and cannot resolve the problem.

When it comes to the health of your elderly mother-in-law, particularly in the context of her refusing to eat and the administration of IV fluids, there are several important considerations to keep in mind.
First and foremost, intravenous (IV) fluids can indeed be life-saving in certain situations, especially for individuals who are unable to maintain adequate hydration and nutrition through oral intake. In your mother-in-law's case, if she is severely dehydrated or malnourished due to her refusal to eat, IV fluids can help restore her hydration levels and provide essential electrolytes. This can be crucial for maintaining bodily functions and preventing complications such as kidney failure, electrolyte imbalances, and other serious health issues.

However, it's important to understand that while IV fluids can provide temporary support, they are not a long-term solution. If your mother-in-law continues to refuse food and fluids, her overall health will likely continue to decline. The duration for which she can survive on IV fluids alone depends on various factors, including her overall health status, the underlying reasons for her refusal to eat, and her body's ability to utilize the fluids and electrolytes provided. Generally, a person can survive for several days to weeks without food, but this varies widely based on individual circumstances.

In addition to IV fluids, hospitals have other interventions that can be considered. For instance, if her refusal to eat is related to psychological issues, such as depression or anxiety, mental health support may be necessary. This could involve consultations with a psychiatrist or psychologist who can assess her mental state and provide appropriate treatment, which may include therapy or medication.

Furthermore, if her refusal to eat is due to physical difficulties, such as swallowing problems or gastrointestinal issues, a speech therapist or a gastroenterologist may be able to provide interventions that could help her regain the ability to eat safely. In some cases, if oral intake is not possible, a feeding tube (such as a nasogastric tube or a PEG tube) may be considered to provide nutrition directly to her stomach.

It's also essential to address the emotional and psychological aspects of her situation. Many elderly individuals may experience feelings of hopelessness or despair, particularly if they are dealing with chronic health issues or disabilities. Engaging her in conversations about her feelings, involving her in decisions about her care, and providing emotional support can be beneficial. Sometimes, family members or caregivers can help by simply being present, listening, and showing that they care.

Ultimately, the best course of action will depend on a thorough assessment by healthcare professionals who can evaluate her specific situation. It may be helpful to have an open discussion with her medical team about her prognosis, the potential benefits and risks of continued IV fluid therapy, and other treatment options that may be available.
In summary, while IV fluids can provide critical support for your mother-in-law's immediate needs, they are not a substitute for comprehensive care that addresses both her physical and emotional health. Engaging with healthcare providers to explore all available options will be key to ensuring she receives the best possible care.
