Why Am I Suddenly Losing Weight?

Why Am I Suddenly Losing Weight?

Losing weight is tough no matter how hard you try, so when the pounds melt away when you’re not trying, you’re right to be concerned. Even if you’re pleased with your looser jeans and slimmer waistline, unintentional weight loss is a red flag.

Our board-certified physicians at The Endocrine Center in Houston, Texas, specialize in pinpointing the underlying causes of unexpected weight loss and can help you resolve the problem. If you still need to lose weight, we can help you do it safely and healthily.

What is unexplained weight loss and when should I worry?

Unexplained weight loss means you’re dropping pounds without trying. In medical terms, it’s losing more than 5% of your body weight over 6-12 months. This kind of weight loss can happen regardless of your age and gender, although it’s more common in people over 65 due to various health conditions. 

Weight fluctuations are normal, but if you notice a steady decline in your weight over several months, pay attention. For instance, if you weigh 200 pounds, a 10-pound loss is concerning. If your typical weight is 140 pounds, losing 7 pounds without trying should prompt a visit to your doctor. 

Older folks and people with weakened immune systems should be especially mindful of unexplained weight loss.

Anything from lifestyle changes to mental health disorders can trigger sudden weight loss, but 72% of cases stem from medical conditions. 

Medical conditions that lead to weight loss

Several medical conditions can cause unexplained weight loss, including, but not limited to:

Overactive thyroid

An overactive thyroid, or hyperthyroidism, occurs when your thyroid gland produces excessive hormones, speeding up your metabolism and leading to sudden weight loss despite an insatiable appetite. Other symptoms may include a rapid heartbeat, mood swings, and increased sweating.

Adrenal insufficiency

Adrenal insufficiency, also known as Addison’s disease, interferes with your adrenal glands’ ability to produce cortisol and aldosterone. The result is unexpected weight loss, fatigue, and dizziness. 

Diabetes

Diabetes often goes hand in hand with obesity, but uncontrolled type 1 diabetes can lead to weight loss. As your body struggles to use glucose for energy, it turns to fat and muscle instead, so your body mass decreases. 

High blood calcium

Hypercalcemia — elevated calcium levels in your blood — can cause digestive problems and weight loss. Overactive parathyroid glands, excessive supplements, or certain medications often trigger this condition.

Mental health and weight loss

Mental health also plays a role in weight management, particularly when it involves changes in appetite.

Depression

Depression suppresses your appetite, leading to weight loss. Plus, the lack of motivation and energy associated with depression makes some people less likely to order a burger or dig into a pint of ice cream.

Anxiety

Anxiety decreases your appetite and increases physical activity like fidgeting or pacing. Because stress hormones affect hunger signals, you may skip meals or eat less if you constantly worry. 

Digestive disorders

Digestive issues affect your ability to absorb nutrients, which could lead to weight loss.

Inflammatory bowel disease (IBD)

IBD conditions like Crohn’s disease and ulcerative colitis involve chronic inflammation that affects the digestive tract. Symptoms include diarrhea, vomiting, and abdominal pain, making eating unappealing and nutrient absorption challenging.

Celiac disease

Celiac disease is an autoimmune condition that damages your small intestine when you consume gluten. Damaged intestines can’t absorb nutrients efficiently, and you may lose weight.

Lifestyle factors and weight loss

While medical conditions cause most cases of unexplained weight loss, your everyday habits could also be a problem.

Substance use

Excessive use of tobacco, alcohol, and recreational drugs can suppress your appetite, mess with your body’s ability to absorb nutrients, and interfere with proper digestion.

Medications

Some prescription medications have side effects like nausea, vomiting, or appetite suppression, contributing to weight loss. 

Stress and sleep

Chronic stress can lead to poor eating and sleeping habits. Sleep deprivation, in turn, affects hunger hormones, leading to unintentional weight loss.
